Feature: 1. Designed for use with air compressors, this pneumatic pressure switch controls the start and stop functions by monitoring and adjusting pressure in the air storage tank. 2. Helps extend equipment life by preventing continuous operation, reducing wear and tear on the compressor. 3. Supports electric drive operation and is built with safety-focused design features. 4. Engineered for reliable long-term performance with durable construction and consistent functionality. 5. Constructed from iron, copper, and plastic for robustness and ease of use in various applications. Specification: Item Type: Air Regulator Model: FB-18, Three-Phase 380V, Single Hole Material: Iron / Copper / Plastic Color: Black Drive Mode: Electric Rated Current: 16A Pressure Range: Adjustable start pressure at 5.5 kg/cm², stop pressure at 8 kg/cm² Bottom Thread: 1/4" NPT thread with 6 mm aluminum tube insert Details: This pressure switch is installed on air compressors to automatically control startup and shutdown based on preset pressure thresholds. By regulating pressure in the air storage tank, it allows the compressor to cycle on and off as needed, supporting optimal performance and maintenance. During factory setup, the switch is calibrated to customer-specified pressure settings and a defined pressure differential — for example, the compressor starts when tank pressure drops to 5.5 kg/cm² and stops when it reaches 8 kg/cm².
