This air filter cartridge is made specially for high temperature operating environments.
We have two kinds of aramid available. One is the classical Nomex from America. The other one is also imported from abroad but cheaper.

The technical data are as follows:

Type: Aramid/340
Basic Material		Aramid short fiber needle felt	Long-term use temperature	≤200℃
Weight		340g/m2	Instantaneous using temperature	≤200℃
Thickness		1.0mm	Precision	5um
Air Permeability		200L/m2.s	MERV	MERV11/F6
Strength	Warp	1100N/5cm	Treatment	Stiffening
	Weft	1000N/5cm	Remarks

Remarks:
1. Air permeability measured as P=200Pa.
2. Filtration Precision: Usually refers to the minimum grade of particle size that can be effectively blocked when the primary grime did not establish in the initial state. In actual use process, we can improve the filtration precision by lowering filter velocity and establishing stable primary grime etc.
3. MERV Grade: As the initial determination. ASHARE 52.2 in USA.EN779 in Europe.

Application:
High temperature operating environments.
