Gast 5HCD-10-M533 Piston Air Compressor

Gast 5HCD-10-M533 Piston Air Compressor

The Gast 5HCD-10-M533 is a heavy-duty, dual-cylinder, reciprocating piston, motor-driven air compressor for demanding industrial, marine, and commercial automation applications. Completely oil free operation, 100% pure, contamination free compressed air, this compressor is perfect for instrumentation control lines, dry sprinkler systems, medical/laboratory facilities and low pressure pneumatic automation systems.

The 5HCD-10-M533 is powered by a highly efficient, dual frequency 3-phase electric motor and provides 4.7 CFM free flow at a continuous maximum working pressure of 100 PSI (6.89 bar). Featuring a rugged die-cast aluminum cylinder head, stainless steel reed valves, and proprietary Teflon®-filled piston rings, this unit provides outstanding corrosion resistance, superior thermal dissipation, and an extended continuous-duty life cycle of up to 16,000 hours of operation under ideal clean, dust-free conditions.

Features

1. 100% Oil-Less Delivery: Eliminates fluid contamination risks in sensitive control systems, reducing downstream filtration maintenance.
2. Continuous-Duty Performance: Precision-balanced internal components allow a 100% duty cycle, operating reliably at a quiet 73 dBA sound threshold.
3. Dual-Frequency 3-Phase Motor: Multi-voltage configurations enable global deployment across both 50Hz and 60Hz marine or land-based grids.
4. Corrosion-Resistant Hardware: Features an aluminum cylinder head, steel motor enclosure, and high-tensile stainless steel reed valves.
5. High Volumetric Efficiency: Dual-cylinder design achieves high displacement with minimal structural vibration and lower starting torque requirements.

Applications

• Pneumatic control loop instrumentation lines (Marine & Industrial)
• Commercial printing press sheet feeding units
• Medical, laboratory, and dental clean-air environments
• Dry fire protection sprinkler system pressure maintenance
• Automated factory production and packaging lines
• Low-pressure environmental sample extraction systems

Marine Engineer’s Operational Directive

1. Three-Phase Electrical Phase Sequence Alignment: When replacing a dual-voltage compressor on an auxiliary marine grid, always confirm line phase rotation (T1, T2, T3). Incorrect terminal connections will spin the crankshaft backward. While the compressor can pump briefly in reverse, it dramatically compromises internal air cooling flow and reed valve efficiency.
2. Thermal Duty Constraints: Note that this particular M533 variation does not come equipped with internal automatic reset thermal overload protection switches. It is strictly critical that the master electrical distribution panel includes a matched, calibrated three-phase thermal circuit breaker or overload relay scaled to the specific working amperage matrix.
3. Head Leakage Nuance: A minor, low-volume pressure leakage around the die-cast head assembly during initial startup under peak pressure loads is standard for this reciprocating design and does not degrade the targeted CFM airflow rating. Never seal these joints with RTV or anaerobic compounds; use only factory-profiled Gast replacement service gaskets during periodic overhaul routines.
