Extraction of fumes that are
released in the course of using
welding equipment for cutting
and joining non-alloy and
alloy steels, including high-
alloy chromium/nickel steels
with a nickel and chromium
content of ≥ 30%
- Welding fumes containing oil
- Aluminium dust
- Burning or incandescent materials
- Cigarettes
- Aggressive media
- Water and moisture
- Explosive gases and/or dust mixtures
- Dusts with toxic characteristics other than welding fumes
Pulse jet
Minimum 4 bar and maximum 6 bar
Dry and oil-free
50 Ndm³ free air per pulse
- A pressure switch monitors the pressure drop across the filter
cartridges and activates a visual warning signal.
- A flashing lamp is to be fitted. This performs 65 +/- 10
flashes per minute at 700-1000 cd in accordance with ISO-EN
842+A1.
- Warning signal activation at loss of pressure 1500 Pa in the
course of 1 hour or longer acts as a request to exchange the
filter cartridge.
• Install the flashing lamp where it can easily be seen and
connect it in parallel with an alarm lamp on the control
panel SCP, Cont.B or Cont.C.
Display indicating direction of rotation on the motor
If the direction of rotation is incorrect, swap over two phases in
the motor connection box.
