HPDAVV 208-230V 3-Phase Rotary Screw Air Compressor 20HP
Parameters: 20HP / 15KW; 230V/60Hz; 3ph; Air Flow 81 CFM; NPT 3/4” outlet; Max 125 psi; Full Load Amps 47. Includes a Spin-on Oil Separator for simple maintenance and reduced oil carryover back to the air end.
HPDAVV Total Rotary Screw With Vertical Tank 7.5HP
Parameters: 7.5HP / 5.5KW; 230V / 60Hz; 3ph; Air Flow 23 CFM; Max Working Pressure 150 psi. Features an intelligent microprocessor control with a simple display and a 60-gallon ASME tank, delivering stable air for intermittent heavy-duty use with a compact footprint.
HPDMC PACK15-TA 20HP Rotary Screw With Dryer
Parameters: 20HP; 230V / 3Ph; 81 CFM; Max 150 psi; 3600 rpm; Spin-on Oil Separator. All-in-one unit includes dryer and 80-gallon tank, compact install, and easy maintenance. Durable construction supports longer service life and efficient operation in demanding environments.
Buying Guide: Key Purchase Considerations
- Horsepower vs. airflow requirements: Higher HP typically yields greater CFM, supporting more tools and faster cycles. Match CFM to peak demand to avoid pressure drops.
- Voltage and phase compatibility: Ensure the unit’s voltage (230V, 460V) and 3-phase configuration aligns with your facility electrical system and distribution panels.
- Air end temperature and aftercooling: Look for aftercoolers and integrated oil separators to reduce oil carryover and discharge air temperatures, improving air quality for downstream tools.
- Tank size and pressurization: Tanks (including vertical tanks) help stabilize surge loads. Larger tanks provide longer run times between cycles but require more floor space.
- Integrated dryer and filtration: For compressed air quality, consider packages with refrigerated dryers and Spin-on filters to remove moisture and oil contaminants.
- Maintenance and serviceability: Models with modular components, easy-access panels, and robust microprocessor controllers minimize downtime and simplify service intervals.
- Footprint and installation: Heavy-duty industrial compressors require concrete pads and proper mounting. Evaluate base mounts vs. tank-equipped configurations for your space.
- Reliability and warranty: Choose units with established after-sales support networks and clear parts availability to maximize uptime.
Comparative Perspectives
- Industrial throughput: For continuous production lines, 20HP-class models with 80+ CFM and 125–150 psi output provide ample headroom over smaller 7.5–10HP options.
- Energy efficiency: Look for microprocessor-controlled controls and efficient air-end designs to reduce running costs over time, especially in high-demand setups.
- Space and installation: If floor space is limited, compact base-mount units or vertical-tank configurations can optimize layout without sacrificing performance.
- Quality of air: Integrated oil separators and optional dryers improve downstream tool performance and reduce maintenance frequency due to oil carryover.
