|product long description||
For our screw filter, we distinguish between three areas:
product long description
Gas filters, particle filters, combined filters and
The gas filters protect against vapours of organic
compounds with a boiling point smaller than 65 °C (A),
(AX) and higher than 65 °C (A), inorganic gases and
vapours (B), sulphur dioxide (E) and ammonia (K).
Our product range includes filters that individually cover
all power ranges as well as multi-range filters that
various power ranges.
Our screw gas filters mainly correspond to
the gas filter class 2.
The particle filters are divided into three classes.
Particle filters of protection class P1 protect against smoke,
mist and dusts of inert substances.
Particle filters of protection class P2 protect against smoke,
mist and dusts of inert substances.
Particle filters of the protection class P3 protect against smoke,
mist and dusts of toxic substances.
Our product range offers you screw filters for
protection class P3.
Combined filters combine the protection of a gas and particle filter in one product
Our product range also includes combined filters
with protection against mercury vapours (Hg).
The product range of our special filters also offers
protection against mercury vapours (Hg) and nitrous gases
gases and nitric oxide ((NO).
Combined filter according to DIN EN 14387:2008 – Filter type / filter class A2 B2-P3 R D
as part of a respirator according to DIN EN 133 - filter device
respiratory protection filter
|product group description||
The protection objective of supplying the wearer of a respirator with pure breathing air is achieved
product group description
by filtering the harmful substances by means of a gas, particle or combined filters. Filtering devices
can remove and store certain pollutants from the ambient atmosphere
within the limits of their separative or absorption capacity depending on the filtering type.
|product series description||
All filters have a high-quality housing made of an aluminum alloy coated on the inside.
product series description
They are compact in design and powerful with a very low weight.
