Airsafe

Airsafe G3 media rolls (SKU ASF04004) are rated G3 per EN 779 and ISO Coarse 45% per ISO 16890. Each roll measures 20 meters by 1 meter, with a polyester media thickness of 14 mm. The media delivers a flow rate of 5610 m³/h/m² and an initial pressure drop of 23 Pa. This grade is suitable for pre-filtration in HVAC and industrial ventilation systems where coarse particulate removal is required. The polyester construction supports moderate humidity and maintains structural integrity under continuous airflow.

Airsafe G4 media (SKU ASF04006) offers a higher filtration efficiency than G3, classified as ISO Coarse 50% per ISO 16890. It has a thicker polyester construction at 20 mm, which contributes to a lower flow rate of 5040 m³/h/m² and a higher initial pressure drop of 36 Pa. The G4 grade is appropriate for applications requiring finer particulate capture, such as final filtration in light commercial HVAC systems. The increased thickness also provides greater dust-holding capacity, extending service life between replacements.

Airsafe cassette filters, such as the Airsafe 57 model (SKU ASF02004), are constructed from non-woven fabric and provide antifungal efficacy exceeding 99%. This makes them suitable for ceiling-mounted installations in environments where microbial growth is a concern, such as healthcare facilities or humid climates. The catalytic filtration action also helps reduce odors and airborne contaminants. The cassette measures 57x57 cm and contains two filter elements, designed for easy integration into standard ceiling grid systems.

Yes, Airsafe media rolls are supplied in standardized widths and lengths—typically 20 meters by 1 meter—specifically for on-site cutting. This allows maintenance teams to trim the media to fit existing ductwork, air-handling units, or filter frames without requiring custom manufacturing. The polyester material is easy to cut with standard tools and maintains its edge integrity. This flexibility reduces inventory requirements and enables quick replacement in emergency maintenance scenarios.

Airsafe G2 media (SKU ASF04002) has an initial pressure drop of 25 Pa and a final recommended pressure drop of 250 Pa. The flow rate is 5400 m³/h/m², and the media is classified as ISO Coarse 45% per ISO 16890. The low initial pressure drop minimizes energy consumption in the ventilation system, while the 250 Pa final limit indicates the point at which the filter should be replaced to avoid excessive strain on the fan. This makes G2 media a cost-effective pre-filter option for high-volume airflows.

Airsafe split-configuration filters, such as the Airsafe 38 model (SKU ASF02002), are designed for HVAC systems requiring efficient particulate removal in confined spaces. The 38x80 cm dimensions and two-filter split configuration allow for installation in cabinet-style air handling units or duct-mounted filter banks. These filters target dust, pollen, and tobacco residue, making them suitable for commercial buildings, offices, and retail environments. The split design simplifies handling and replacement, reducing downtime during maintenance.
