P-E-3 filter element

      The filter consists of the cylindrical iron shell and activated carbon-catalyst impregnated with different chemicals inside, with a standard universal thread of M40*4 with interchangeability, and yellow labels. The filter provides defense against acidic gas and vapor, including sulfur dioxide, chlorine, hydrogen sulfide, nitrogen oxides, phosgene, sulfur trioxide, cyanogen chloride, phosphorus and chlorine-containing organic pesticides, etc.

Technical requirements:

Ventilation resistance: ≤ 200 (30 L/min) ≤ 770 (95 L/min)

Dust discharge capacity of filter: E filter ≤ 0.12 mg

Sealing: no bubbles should escape within 1 min under the pressure of (15±2) KPa.

Protective time for sulfur dioxide (SO2): ≥ 30 min (test gas concentration 13.3 mg/L)

      The protective time is inversely proportional to the concentration of toxic agent. The higher the concentration, the shorter the effective protective time.

      This type of filter must be used in conjunction with the full face mask through the breathing hose.
