European Style Air Compressor Pressure Switch Assembly for 220V and 380V Systems
This European style pressure switch assembly is a core component for regulating and controlling air compressor systems. Designed for integration into industrial, workshop, and professional setups, it offers a defined switching pressure range of 0.5 to 0.8 MPA, equivalent to 5-8 BAR or 90-120 PSI. Available in two voltage configurations—220V and 380V—it provides flexibility for different electrical infrastructures. The assembly is built to handle a maximum current of 20A and comes with standardised connection points, including a 12mm (1/4 inch) connector and a 6mm exhaust pipe, facilitating straightforward installation into existing air lines.
Technical Specifications and Build
This pressure regulating valve is defined by its concrete technical ratings and physical dimensions, providing the necessary data for system integration and compatibility checks.
Electrical Ratings and Pressure Range
The switch's primary function is to activate or deactivate the compressor within a set pressure band. Its switching range is clearly specified as 0.5-0.8 MPA (5-8 BAR, 90-120 PSI), with a working pressure of 5-8 KG. The unit is offered in two distinct models: one for 220V and another for 380V systems, both sharing a maximum current rating of 20A. The contact method is normally closed, and the switch box itself is clearly marked with its maximum tolerances: 240 Volts, 20 Amps, 12 Bar, and 175 PSI.
Physical Dimensions and Connections
The assembly is housed in a compact switch box measuring 185mm in length, 100mm in width, and 110mm in height. This defined size allows for planning in confined control panels or on compressor units. Connection is standardised with a 12mm thread, also noted as a 1/4 inch fitting, for the main inlet/outlet. A 6mm exhaust pipe and a pressure relief port with an outer diameter of 9.5mm complete the connection suite, providing the necessary outlets for safe system operation.
Durability and Practical Application
Beyond its specifications, the product's value lies in its stated longevity and the practical scenarios where such a component is essential.
Rated Lifespan and Cycle Endurance
A key metric for any switching component is its operational life. This pressure switch has a rated mechanical life of 80,000 cycles. This figure indicates the number of on/off pressure cycles the switch is designed to endure under normal working conditions, informing expectations for maintenance intervals and long-term reliability in repetitive use environments.
Integration into Air Systems
This assembly is suited for scenarios requiring automatic pressure regulation in compressed air systems. Its typical use is on air receiver tanks or compressor control panels, where it monitors pressure and switches the compressor motor on or off to maintain the desired air pressure within the specified 5-8 BAR range. The availability of 220V and 380V models covers the common single-phase and three-phase power supplies found in workshops and light industrial settings.
Value and Selection Guidance
Understanding the product's tangible attributes helps in assessing its suitability and value for specific compressed air applications.
Replacement and System Compatibility
This unit serves as a direct replacement or upgrade part for compressors using a European-style pressure switch with a 12mm connector. The clear labelling of voltage options (220V or 380V) and the provided pressure range allow users to match the component precisely to their system's requirements, ensuring correct operation and avoiding electrical incompatibility.
Why Choose This Pressure Switch
The decision to use this assembly is supported by its specific, measurable data: a clear pressure range, a choice of standard voltages, a high cycle-count lifespan, and defined physical connections. It avoids guesswork for installers and provides a component built to a known set of industrial parameters, focusing on functional reliability within its stated specifications rather than unsupported claims of superiority.
