Frequently Asked Questions

Q: Can this filter maintain air purity in high-heat industrial ovens?

Absolutely. It is specifically designed for ovens with requirements on clean air, offering G3 efficiency to effectively capture particles while withstanding a maximum temperature of 300°C.

Q: Will the filter fit into a compact or space-constrained drying tunnel?

Yes. Its thin thickness and flat panel design (available in 21mm and 46mm) allow for seamless integration into even the most compact ventilation slots without sacrificing thermal performance.

Q: How does the low resistance design benefit my production line?

The filter maintains an incredibly low resistance of 40Pa. This ensures your high-temp ventilation system runs at peak energy efficiency, reducing operational noise and long-term electricity costs.

Q: Is there any risk of the filter media shedding during high-velocity heat cycles?

No. The filter features a robust aluminum net face guard on both sides. This protection prevents media migration and ensures structural stability during intense heating in drying ovens or tunnels.

Q: What materials are used for the frame to prevent off-gassing at 300°C?

We use durable Aluminum or Galvanized steel frames. These materials are chosen for their thermal stability and durability, ensuring no harmful gasses are released into your clean heating environment.
