Maintenance units
Common features
• High flow volumes with low pressure drop reduce the energy costs
• Flexible installation thanks to modular principle; assembly possible on
right or left
• High control accuracy
• Maintenance-free operation
Pressure reducer
Pressure reducer 1/4“
Type Art. no.
Connecting
thread
Robust maintenance units with metal housing for an air-flow volume of up to 3000
l/min.
• Bleed function for quick, precise regulation
• Pressure regulator with piston for high operational
reliability
• High secondary pressure stability (adjusting
pressure), even if the input pressure orthe
flow rate changes
• Locking control knob
• Installation independent of flow direction
because pressure gauge can be connected
on both sides
• Regulation range 0-12 bar
• Standard features include: pressure gauge
• For installation in machines or mounting on
walls. Can be integrated in control panels

Flow charts: Measurement carried out at admission
pressure of8bar. The set pressure can be
read at the far left (2, 4and 6bar). Example: pressure
reducer 1/4“: set value 6bar. At700 l/min.,
5bar is available after the pressure reducer.
