The demand valve for industrial respiratory protection
AirValve's positive and negative pressure versions are particularly resistant to contamination and work reliably in the toughest conditions.
Where there are high concentrations of contaminants, heavy soiling and limited escape routes - wherever totally reliable respiratory protection is required.
AirValves N and P for negative and excess pressure
Streamlined technology ensures greater safety in use
AirValve N is available as a negative pressure version with Rd 40 standard thread connection to EN 148-1 or as a positive pressure version AirValve P with M45x3 connection to EN 148-3.
Optional warning signal
An audible warning is given to the carrier in the event of a supply pressure failure.
Clear technology
By eliminating vulnerable small parts, the technology has been reduced to robust core components.
Innovative shut-off function for positive pressure variant
Positive pressure demand valve feature a shut-off function to prevent uncontrolled loss of air when the apparatus is not in use. The AirValve P shut-off can be operated by a large area membrane. Additional seals are not needed.
