Industrial Applications

1. Main Air Preparation for Automated Palletizing Systems

Serves as the primary air entry point for high-speed packaging and palletizing machinery, conditioning plant air before it reaches valve manifolds and actuator banks.

Problem Solved

Protects sensitive directional control valves from pipe scale and rust (via 40µm filtration) while stepping down fluctuating plant airline pressure (up to 20 bar) to a stable operating pressure (typically 6 bar) to ensure consistent actuator speed and force.

Standard nominal flow rate 4500 l/minGrade of filtration 40 µmOperating pressure 0.8 bar ... 20 barPneumatic connection G1/2

2. Pneumatic Supply for Semi-Automated Assembly Stations

Regulates compressed air for a cluster of manual pneumatic tools (impact wrenches, rivet guns) and clamping fixtures at an operator workstation.

Problem Solved

Provides a high-flow, stable air supply (low hysteresis of 0.25 bar) to prevent tool torque fluctuation, while the manual condensate drain allows the operator to easily purge moisture build-up at the start of each shift without complex automated wiring.

Pressure regulation range 0.5 bar ... 12 barMax. pressure hysteresis 0.25 barCondensate drain Manually rotatingPlastic bowl guard

3. Air Supply Regulation for Pneumatic Component Test Benches

Functions as the adjustable pressure source for testing capabilities of pneumatic cylinders, valves, and grippers in a quality control lab or R&D facility.

Problem Solved

Enables precise verification of component performance across a wide pressure spectrum (0.5 to 12 bar) using the rotary knob, ensuring components meet specifications for both low-pressure sensitivity and high-pressure durability.
