About this F9 Rigid Bag Filter Compact Cassette
F9 Rigid Bag Filter, also known as a Compact Cassette Filter, or Minipleat Compact Filter, is a high efficiency final filter. These filters excel at eliminating microscopic particles, including auto emissions and welding fumes. Crafted with an anti-crash polystyrene hard plastic frame, boasting a depth of 292mm, these filters exemplify durability and lightweight construction. With an impressive burst resistance, minimal pressure drop, and high dust holding capacity, they are the ideal choice for demanding operating conditions, such as gas turbine air intake applications.
Rated Airflow:
24x24x12 = 4250 m3hr
24x20x12 = 3500m3hr
24x12x12 = 2125m3hr
Initial Pressure Drop: 105 Pa @ 3.17m/s (or 80Pa @ 2.54m/s)
Recommend Final Resistance: 635Pa
Applications
Our filters are purposefully crafted for supply, exhaust, and recirculation in HVAC installations that demand the utmost air cleanliness. With a compact design, expanded surface area, and minimal initial resistance, they serve as an excellent substitute for conventional Bag filters & Panel filters with comparable efficiencies. These filters boast a low-pressure drop and exhibit a high dust holding capacity, ensuring effective and reliable air filtration.
Characteristics
The filter media is made of water-resistant micro-fine glass fibre filter media that is tightly pleated and separated by continuous thermo-plastic bead separators. This design allows for a large amount of filter media, resulting in a longer service life and low pressure drop. The Mini-Pleated media packs are perfectly V-shaped and sealed to the surrounding frame.
