Z-K-P3-2 filter element

      The filter mainly consists of the cylindrical aluminum shell and activated carbon-catalyst impregnated with different metal oxides, and smoke filter made of high-efficiency glass fiber filter paper, with a standard universal thread of M40*4 with interchangeability, and green + pink 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, toxic smoke and toxic smog.

Technical requirements:

Ventilation resistance: ≤ 140 (30 L/min) ≤ 610 (95 L/min)

Dust discharge capacity of filter: K filter ≤ 0.12 mg

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

Protective time for ammonia (NH3): ≥ 25min (test gas concentration 2.1mg/L)

Smoke filtering performance ≥99.99%

      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 can be used in direct conjunction with the full face mask.
