Air Compressor Pressure Switch Assembly (220V, 1/4" Valves)

Compressor automation block (220V pressure switch) assembly with regulator, 2 pressure gauges, and valves (1/2" – 2x1/4")

Main connection parameters:

• main 20mm — bottom threaded connection to the compressor receiver (1/2" Male / ~20 mm).

• 2*1/4" — regulator outlets with valves (1/4" / ~12.5–13 mm) for hose connection.

• hand crank — pressure regulator with a manual knob (red handwheel handle).

Pressure switch assembly for piston compressor (220V) — this is a complete control module designed to automatically start and stop the compressor motor when specified pressure parameters are reached in the receiver. The kit is equipped with a built-in regulator for adjusting output pressure, two pressure gauges (to monitor receiver and output pressure), and two ball valves for simultaneous connection of two pneumatic tools.

Main advantages and features:

• Ready-to-install kit: Includes a pressure switch, manifold (four-way), pressure regulator, 2 pressure gauges, and 2 output ball valves.
• Automatic compressor operation: Stops the motor when the upper pressure threshold is reached (typically 8 bar) and restarts when it drops below 6 bar.
• Smooth pressure adjustment: The regulator with a convenient manual hand crank allows for easy setting of the required working pressure for spray guns or pneumatic tools.
• Two independent outputs: 1/4" ball valves allow for connecting two pneumatic hoses simultaneously with independent air supply shut-off.
• Manual start/stop button: The red button on top of the cover allows for manual power disconnection at any time.

Compatibility and application:

• Compressor type: Piston oil and oil-free air compressors powered by a 220V network with receiver volumes from 24 to 100 liters.
• Compatible brands: Dnipro-M, Werk, Forte, Miol, Sigma, Metabo, Hyundai, Intertool, Einhell, Denzel, and most similar Chinese and European-made compressors.
