Element ELT-4 Three-Phase Mechanical Pressure Switch
Based on the industrial design and engineering standards of the Element control series, the Element ELT-4 is a heavy-duty mechanical pressure switch built for regulating the automatic operation of three-phase industrial air compressors, booster systems, and hydrophore water pumping equipment. Acting as a robust, non-digital line controller, it mechanically cycles high-power three-phase motor loads directly by monitoring the fluid or gas pressure thresholds inside an connected pressure vessel or pneumatic line.
Key Features
-
High-Capacity Multi-Phase Contact Interrupter: Features a robust internal three-phase contact mechanism designed to securely break or connect high-current motor pathways without requiring an intermediate control relay.
-
Integrated Manual ON/OFF Safety Toggle: Outfitted with an external 2-position manual toggle lever at the base of the plastic housing, allowing operators to safely isolate the pump or compressor system during standard maintenance or emergencies.
-
Heavy-Duty Protective Enclosure: Covered by an impact-resistant, thick matte plastic canopy that completely seals the internal micro-switch contacts and calibration springs against industrial airborne particles, dust sifts, and moisture drops.
-
Heavy Aluminum Die-Cast Base Manifold: Built upon a durable metallic connection manifold containing standard female threaded connection ports, ensuring airtight integration onto receiver tanks, air loops, or heavy plumbing fittings.
-
Adjustable Operational Setpoints: Designed with internal spring-loaded adjustment screws located beneath the cover canopy, giving technicians the ability to field-calibrate both the cut-in (system start) and cut-out (system stop) pressure values.

Applications
-
Industrial Air Compressor Automation: Directly manages heavy-duty three-phase piston or screw-type air compressors by automatically turning the motor off when the air receiver reaches peak storage capacity, and restarting it as air tools consume the reserve.
-
Commercial Building Water Booster Stations: Regulates large multi-phase booster pumps inside high-rise facilities or commercial infrastructure to maintain a reliable water flow across plumbing networks.
-
Agricultural Hydrophore Systems: Installed onto deep-well water extraction reservoirs to monitor fluid pressure loops, preventing excessive pressure stress on distribution pipelines.
-
Pneumatic Machinery Safety Systems: Serves as a reliable, non-electronic mechanical fallback to prevent system over-pressurization inside industrial pressure vessels and processing plants.
