Filter nonwoven fabric G4 Recuperation filter 20mm 500cm x 100cm x 2cm 5m2
Bitmat filter fabric for G4 recuperators is a nonwoven fabric for pre-filter, designed to protect the recuperator heat exchanger from larger contaminants. Thanks to its construction, it works well both in recuperators and in air handling units, as well as other HVAC devices.
Bitmat is a manufacturer and distributor of the highest quality technical materials.
1 piece = 500 x 100 cm
2 pieces = 1000 x 100 cm
3 pieces = 1500 x 100 cm
4 pieces = 2000 x 100 cm
Nonwoven fabric made from 100% polyester fibres. Thanks to the use of an appropriate blend of fibers, it is characterized by high elasticity and resistance to deformation. Compliant with PN-EN ISO 16890. ISO COARSE 40%.
Key advantages of the filter mat:
- excellent pre-filtration
- waterproof
- versatility: compatible with all air handling units
- ease of processing: simple cutting to the desired size
The tests were carried out in accordance with the requirements of the PN-EN ISO 16890 series of standards.
- PN-EN ISO 16890-2:2023-01 Dust-proof air filters for general ventilation:
- Measurement of filtration efficiency as a function of particle dimension and air flow resistance.
- EN ISO 16890-3:2017-01 Dust-proof air filters for general ventilation.
- Determination of filtration efficiency by gravimetric method and air flow resistance depending on the mass of dust retained
- EN ISO 16890-4:2023-01 Dust-proof air filters for general ventilation.
- Seasoning method to determine minimum fractional efficacy.
The filter classification was based on the standard:
- EN ISO 16890-1:2017-01 Dust-proof air filters for general ventilation.
- Technical specifications, requirements and performance classification system based on dust particle size (ePM).
- The filter performance study was conducted for electrically neutralized solid potassium chloride (KCI) particles and test dust A2 according to ISO 12103-1.
Technical specification:
- thickness: 20 mm
- weight 220 g/m2
- dimensions: 5m x 1m
- resistance to moisture:
- self-extinguishing and flame retardant
- Meets the requirements of OEKO-TEX Standard 100, hygienic according to PZH and Intertek
- Initial flow resistance 91 Pa
- Average dust retention value 53,79%
- Dust absorption: 276,10 g
- Final flow resistance 200 Pa
According to ISO 16890-2:
- 50% nominal flow rate, gives a flow rate of 0,470 m3/s and a flow resistance of 32 Pa
- 75% of nominal flow, gives a flow rate of 0,708 m3/s and a flow resistance of 58 Pa
- 100% nominal flow rate, gives 0,944m3/s flow rate and 91Pa flow resistance
- 125% nominal flow rate, gives a flow rate of 1,180 m3/s and a flow resistance of 123 Pa
The filter mat is made of high quality polyester fabric, which guarantees the right density and ensures optimal airflow through the ventilation unit. In addition, the polyester fibers used make the filter waterproof, does not absorb moisture and is resistant to various environmental factors.
The frequency of pre-filter replacement depends on various factors such as the level of air pollution or its humidity, but a significant proportion of manufacturers of ventilation devices recommend replacing the pre-filter every 3 months.
Fibre intended for industry, where the pre-filtration process is very important. The spatial structure of the nonwoven fabric provides excellent dust absorption. The main applications are:
- pre-filtration in ventilation systems, air conditioning, control cabinets
- paint shops
Instructions for assembly:
Before starting to replace the filter, disconnect the ventilation unit from the electricity. Then follow the filter replacement instructions that come with the device.
If you are looking for a reliable solution to protect your ventilation system from contamination, our G4 filter fabric is the perfect choice!
