High Efficiency Particulate Air (HEPA) & Ultra Low Particulate Air (ULPA) Filters

High Efficiency Particulate Air (HEPA) filters and Ultra Low Particulate Air (ULPA) filters are made of a spun-hooked glass fibre, rolled into a paper-like material, which is then pleated, increasing the filter’s surface area. FILT AIR’s HEPA and ULPA filters comply with various standards from organizations such as the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), the American Institute of Architects (AIA), and the Joint Commission for the Accreditation of Healthcare Organizations (JCAHO).

HEPA and ULPA filters screen particles larger than 0.3 µm and FILT AIR’s HEPA filters are 99.99% efficient in removing 0.3 µm and larger particles. FILT AIR’s ULPA filters are 99.9995% efficient in removing particles that are 0.12 µm and larger. When these high efficiency filters are used with a prefilter, they can last for several years in a cleanroom environment. In addition to this, because airflow capacity will decrease and the static pressure will increase with time, FILT AIR’s HEPA filters and ULPA filters have the ability to become even more efficient as the filter loads.

HEPA and ULPA filters are used widely in air filtration and purification systems to control airborne particulate levels and to stop the spread of toxic agents or infectious diseases. FILT AIR’s HEPA filters are often used in HVAC systems, biological safety cabinets (such as the Bio Safe), laminar flow hoods, and various healthcare facilities worldwide. Laminar flow hoods are not designed to control infectious diseases or toxins, but medical facilities such as isolation rooms (the IsoArk™), Intensive Care Units (ICU’s), and surgical centres / operating rooms also use HEPA filters and ULPA filters to remove infection and contamination by airborne microorganisms such as viruses, moulds, and spores.

Specially designed for use in cleanrooms and precision assembly areas, FILT AIR’s HEPA and ULPA filters come in a wide range of sizes for many applications. They can also be used in final-filtration applications with purification filters. The filtration medium consists of highly efficient microporous polyurethane minipleats that are held in place with rigid plastic separators that keep the filter medium from nesting together. The design channels the air flow with optimal efficiency and reduces resistance. The filter is sealed into a sturdy aluminium frame with a fire-retardant adhesive.

There are several important provisions to consider when looking for HEPA filters and ULPA filters, including: porosity, efficiency, filter length, height and width or ring size, and ply. Filter porosity is measured by the average number of pores-per-linear-inch (ppi), which provides an open cell that offers little air restriction to fine-celled foam for maximum particulate filtration. Efficiency is the ability of HEPA filters and ULPA filters to remove a certain amount of particles of a certain size with a specific airflow. Ply refers to the layers of media that are contained in the filter. The filter’s ply can be anywhere from one to five, and in special circumstances even greater than five.

All of FILT AIR’s HEPA filters are tested for air flow resistance and DOP (dioctylphthalate) smoke penetration with a mean particle diameter of 0.3 microns by measuring upstream and downstream concentrations with a laser, achieving the rating of 99.99% efficiency with particles 0.3 microns or larger in diameter.

Since different processes of air filtration and purification need different levels of air cleansing and purification, at FILT AIR we help to analyze and specify your requirements, producing a match for your specific needs and FILT AIR Ltd. has developed a complete range of high efficiency filtration solutions.

Terminal Filter

Clean environments often require terminal filters that can be connected directly to the air supply or the planum.

Clean areas such as cleanrooms face a range of filter challenges, including lack of ceiling space, filter maintenance, and filter replacement. Yet with our terminal filters, you need not worry.

Over the past two decades, Filt-Air has delivered large quantities of terminal filters to a range of facilities and industries, including pharma, security, and microelectronics.

The Filt-Air terminal filters provide a range of unique advantages, including:

  • Innovative designs
  • Flexible filter housing sizes
  • Simple-to-replace filters – and simple to access

Fan Filter Unit

Fan Filter Units (FFU) are most frequently seen in cleanrooms, which are actively cleansed, well isolated, and have low concentrations of airborne particles.

The FFU is an essential element in cleanrooms in semiconductor manufacturing, the pharmaceutical industry, scientific research laboratories, and other facilities that require a controlled environment.

The Filt-Air FFU is a combined device within a special housing, which includes a high efficiency filter and a blower, and can also include an electronic controlling system. Multiple FFU devices can be installed on the cleanroom ceiling, in line with the specific requirements of each cleanroom and classification.

When choosing an FFU, it is important to check the following information:

  1. Power consumption and control system
  2. Noise level
  3. Unit heights (especially in low ceiling facilities)
  4. Airflow vs. pressure drop

Fan Filter Unit

Certain extra-precise measuring devices, special engineering machinery, and semiconductor manufacturing areas require the highest level of classification.

Class 1 is considered the cleanest cleanroom, with more than 500 air changes per hour and a ceiling coverage of up to 100%.

For the past two decades, Filt-Air has specialized in developing and manufacturing high-end equipment for Class 1 cleanrooms, for semiconductor industries around the globe, including military systems, measuring equipment, and many other high technology industries.

The Filt-Air FFU for Class 1 cleanrooms is a cutting edge, high technology device, capable of supplying large amounts of filtered air into the required space.

Safe Change Housing (BIBO)

Facilities for dealing with biological, chemical, and radioactive hazardous materials are required to have a safe change housing for the contaminated filters. Such systems are also known as Bag in Bag out (BIBO).

The advantage of the Filt-Air safe change housing system is its proven isolation capabilities during the casual operation and the replacing of decontaminated filters.

Over the years, we have supplied hundreds of BIBO systems for laboratories, BIBO units for nuclear research centers, safe change housing systems for hospitals, and so much more.

Filt-Air provides its customers with customized solutions for varied environments and conditions, using a range of materials (e.g. coated steel, stainless steel 304 or 316), and adapted to any airflow and conditions.

Clean Tent

In some cases, a cleanroom may be required for achieving higher classification of a specific area. Yet building a cleanroom may not always possible (due to lack of space, for example); moreover, specifications may require the installation of a higher classification room within an existing cleanroom. One optimal solution is the building of a Filt-Air clean tent.

This solution includes an FFU system that covers a specific area and has a variety of options for side coverings.

Filt-Air has produced numerous clean tents for the pharma industry, mini-clean environments for the food industry, and even small clean areas for mechanic or electronic assembly. These solutions are tailored to our customers’ specific needs, and can be operated and controlled with the greatest of ease.

Oil Mist Collector

Some CNC machines use oil for cooling and other processes the worked-on surface (such as when milling or drilling). Yet this results in the hazardous dispersion of oil mist into the air – which may then be inhaled by humans nearby. As this poses a serious health hazard, health authorities around the globe have begun to enforce the use of oil mist collectors, to prevent such inhalation.

The innovative Filt-Air oil mist collector has a unique geometric design, to provide excellent separation capabilities and protect CNC operators and other workers in the vicinity – and ensure a safe and healthy workspace.

Panel / Compact Filters

One of the most common air filtration products (high efficiency filtration) are panel filters and compact filters, applied in a variety of industries. These include filters for HVAC, cleanrooms, clean environments, healthcare facilities, laboratories, and more.

Both the panel filter and the compact filter (also known as v-shape or v-bank filter) are based on a pleated structure. It is this structure that allows greater quantities of air to pass through the filter, while reducing pressure and accumulating more dust and particles within the filter due to increase of the filtration area.

The Filt-Air panel filters and compact filters offer customers advantages:

  • Special sizes tailored to your needs. In addition to standard filter sizes, we are able to deliver almost any size required.
  • Precise pleating technology. This unique capability ensures greater efficiency and durability over time.
  • Customized production of filter frames using a variety of materials (including. ABS, coated steel, and stainless steel), latches and handles, to meet specific standards and regulations.

Terminal Filter

Clean environments often require terminal filters that can be connected directly to the air supply or the planum.

Clean areas such as cleanrooms face a range of filter challenges, including lack of ceiling space, filter maintenance, and filter replacement. Yet with our terminal filters, you need not worry.

The Filt-Air terminal filters provide a range of unique advantages, including:

  • Innovative designs
  • Flexible filter housing sizes
  • Simple-to-replace filters – and simple to access

Also referred to as carbon filters, the Filt-Air gas absorption filters prevent penetration of gases into a given space. These gas absorption filters differ from partial filtration solutions (such as Fine Dust, HEPA, and ULPA), as they contain active carbon that can absorb a variety of gases. The filters may contain either granules of active carbon or a combined particle filtration media that is soaked with carbon – to ensure optimal outcomes.

The use of carbon filters is of the utmost importance for industries who deal with harmful gases, including biological institutes, chemistry manufacturers, radioactive research centers, and semiconductor manufacturers. In addition, these are widely used by defense authorities for protection against CBRN threats.

Our main advantage in the field of gas absorption filters is that we are a member of the BE Group, who began their activity in this field more than 50 years ago.

Power Stations / Gas Turbines

In today’s world, gas turbines are one of the most widely used power generating technologies. Gas turbines are a type of internal combustion engine, in which the burning of an air-fuel mixture produces hot gases that spin turbines, converting them into power.

As this process consumes huge quantities of air, it needs to be treated properly. Air contains a variety of elements, especially different sized particles – which could affect the efficiency of such power stations or even seriously damage them.

By employing innovative engineering capabilities, Filt-Air’s gas turbine filters enable increased air quantities combined with decreased pressure drops. This is especially important as poor inlet filtration could lead to significant erosion of surfaces (by approx. 10-micron particles), fouling of compressor blades (by 2–10-micron particles), and corrosion due to salts and acids. As such degradation processes are irreversible, they could result in serious damage to extremely costly turbines, while decreasing power generation.
