Cardboard Filter – G90-C Series

Compact Fine Dust / HEPA Filter

Card Board Filter
Card Board Filter
Design

Filter Media

The G90 series is produced using a special pretested blend of cotton and polyester fibres. The G90 media has extra pleats (more sq. ft. of space) for increased dust holding capacity.

Media Support

The media is bonded to a special galvanized steel expanded metal support grid with a 95% open face area. This allows increased utilization of the filter media. The media and metal combination is designed to prevent sagging or collapse and is bonded tightly to the frame, eliminating any possibility of air bypass.

Enclosure Frame

The G90 enclosure frame is a special die cut solid craft-board with extra moisture resistance, designed to prevent collapse under extremely humid conditions.

Testing
  • Each HEPA filter is tested and packed in ­accordance with American Standard IEST-RP-CC001.3 (HEPA and ULPA Filters), in accordance with the ­European standard EN 1822-1 4&5 ­(Testing filter elements HEPA and ULPA efficiency and scan method), or customer requested testing.
    The prefilters are tested in accordance with European Standard EN 779 (Particulate air filters for general ventilation). This standard is based on ASHRAE 52.1 (Gravimetric and Dust-Spot ­Procedures for Testing Air Cleaning Devices Used in General Ventilation for Removing ­Particulate Matter, 1992).
  • The XY-scan testing device is able to ­perform automated filter leak testing of high efficiency air filters using automatic particle counters and a motorized scan table. While the particle counter probe passes over the filter face, the computer compares the counted particles with the given leak tolerance setting. In addition, it calculates the overall ­efficiency for each checked filter and measures the pressure drop @ nominal airflow.
Features
  • Efficiencies of 45% up to 95% ASHRAE
  • High quality standard due to Quality Assurance System
  • Header consists of corrosion resistant plastic frame
Standards
  • EN 779
  • ASHRAE 52.1
  • ISO 9001:2000

The G90 series is produced using a special pretested blend of cotton and polyester fibres. The G90 media has extra pleats (more sq. ft. of space) for increased dust holding capacity.

The G90 Series is designed for a longer lifetime with reduced maintenance costs. All G90 filters are designed for easy installation in existing HVAC systems and perform well as the primary filter or as a prefilter for extending the life of a high efficiency filter.

The G90 filters have an average efficiency of 30% to 60%. All testing is done in accordance with the ASHRAE 52-1 standard guidelines. The G90 filter has more media area for improved performance and longevity. The G90 filter is designed for applications requiring higher efficiency and arrestance. All units are available in 1”, 2”, and 4” thicknesses.

The G90 1”, 2”, and 4” filters are available in unlimited sizes. This will make increased efficiency available in all applications.

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:

  • Septal 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.

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
