The pvc full face mask, comprising a hood, face mask and filter, provides comprehensive protection for the head, neck and neck against agents such as water, dust, certain chemical substances ...(depending on the filter) The half mask is made of flexible black rubber. The material, its shape and dimensions make it comfortable to wear. The mask has an exhalation valve and 2 threaded ports. The filters can be easily replaced (replacement filter sets are sold separately)
pvc full face mask
- Model 756
- made of unlined pvc
- transparent pvc visor
- changeable filters
pvc full face mask main part
- made of thermoplastic rubber
- houses the two filters connectors and exhalation valve
- the design and material used prevents air from entering the interior of the mask
- adjustable 2-band head strap
Filters
- two filters: type a1; according to en 141
- compatible with 755/756 filters
Application
This equipment the pvc full face mask is ideal for any situation that requires respiratory protection and head protection.
With the A1 filters supplied, the mask provides full protection in areas with oxygen concentrations greater than 17% by volume and contaminated
Gases and vapours with a boiling point above 65°C (e.g. solvents or paint) and organic chemicals.

Filter classes (adsorption capacity)
Each filter also carries an indication of the filter class, as the filters are predominantly divided into three classes (1: low to 3: high) according to their adsorption capacity. The class indicates how much the mak (maximum workplace concentration) may be exceeded.
For gas filters a, b, e and k, the maximum gas concentration in class 1 is 1000 ml/m³ (0.1 vol-%), in class 2 5000 ml/m³ (0.5 vol-%) and in class 3 10000 ml/m³ 1 vol-%). There are different maximum periods of use depending on the maximum concentration and the substance (classification according to boiling point). For protection against group 1 substances, the filter may be used for a maximum of 20 minutes at concentrations of 500 ml/m³ and a maximum of 40 minutes at concentrations of 100 ml/m³. Against substances of group 2 the wearing time is limited to 20 minutes at concentrations up to 5000 ml/m³ and 60 minutes at 1000 ml/m³. For the filters No, Hg, Co and Reactor, the manufacturer's specifications regarding duration of use and concentration must be observed. Filter no may be used for a maximum of 20 minutes, filter Hg for a maximum of 50 hours.
