HPDAVV 7.5HP / 60 Gallon Vertical Tank
The HPDAVV 7.5HP single‑phase rotary screw compressor combines a vertical ASME 60‑gallon tank with a compact base‑mounted footprint. It delivers up to 23 CFM at a maximum 150 psi, making it suitable for light production tasks and medium‑duty shop use. Features include microprocessor controls with a clear display to monitor essential parameters and steady operation. A 12‑month parts warranty supports long‑term maintenance programs, while the single‑phase input simplifies electrical setup in smaller spaces. The unit’s integrated oil separator and durable construction are designed to minimize downtime in mixed‑duty environments.
TRIAX Kompressor MV 100 SAE 30 Oil
TRIAX Kompressor MV 100 SAE 30 is an advanced full‑synthetic compressor oil formulated for rotary, vane, screw, and reciprocal systems. Though not a compressor unit itself, this oil is designed to maximize service life in demanding conditions, offering excellent high‑temperature performance, broad climatic tolerance, and extended intervals between oil changes. It reduces wear and protects bearings, delivering a smoother operation in compact or base‑mounted systems. The formula supports up to 20,000 hours of service life when used as part of a compatible, well‑maintained air system, making it a practical upgrade for smaller screw setups seeking durability.
HPDAVV 10HP / 33 CFM 230V/60Hz 3ph
This HPDAVV model targets small‑to‑mid sized production with 33 CFM output at up to 125 psi, powered by a 3‑phase 230V supply. The unit emphasizes stable, continuous operation with an integrated spin‑on air oil separator to simplify maintenance. A robust controller provides essential readouts to monitor performance, while the base‑mount design supports streamlined installation in tight workshops. Its sealing and oil management are designed to minimize downstream oil carryover, making it suitable for a variety of compact industrial applications where space efficiency matters.
HPDAVV 20HP / 81 CFM 125 PSI (460V) Base Mount
For higher demands in a compact footprint, this 20HP model delivers 81 CFM at up to 125 psi. Input is 460V, 60Hz, with a 3‑phase configuration suitable for industrial spaces that have three‑phase power. The design includes an integrated oil separator and a spin‑on oil management system to ease maintenance and oil return to the compressor air end. It is well‑suited for automotive shops, small manufacturing lines, or other environments that require reliable air in limited space, without sacrificing performance.
HPDAVV 208-230 Volt 3-Phase Rotary Screw Air Compressor 20HP
This 20HP, 230V 3‑phase option delivers substantial output with 81 CFM at 125 psi. It uses a spin‑on oil separator to simplify maintenance and reduce oil carryover, supporting cleaner compressed air. The base‑mount installation offers stable operation in tight spaces, and the controller helps manage motor loads and performance. Users should ensure compatible electrical infrastructure for 3‑phase service, but when properly wired, this model provides strong performance for compact, higher‑demand setups.
Buying Guide: Key Purchase Considerations
- Power supply and phase: Determine whether your facility provides single‑phase or three‑phase power. Single‑phase units are easier to install in small shops, but three‑phase models often deliver higher CFM with greater efficiency for continuous use.
- CFM and PSI needs: Match the air flow (CFM) and working pressure (PSI) to your tools. Overestimating capacity wastes energy; underestimating can stall production. For small spaces, aim for the smallest footprint that still meets your peak demand.
- Tank capacity and duty cycle: Larger tanks reduce cycling and provide steadier air delivery, but require more space. Consider duty cycle and how often you will run tools simultaneously.
- Maintenance and oil management: Spin‑on separators and high‑quality synthetic oils extend life and keep air clean. Look for systems with accessible service components and straightforward oil changes.
- Electrical and installation: Check voltage, phase, and amperage requirements. Ensure electrical panels and wiring can support the compressor, and verify that space has proper ventilation and clearance for service access.
- Warranty and support: A solid parts warranty and responsive after‑sales support reduce downtime. Review manufacturer resources and authorized service networks for your region.
- Noise and footprint: If space is tight, consider sound levels and overall dimensions. Some models offer quieter operation and compact footprints suitable for smaller workshops.
- Compatibility and accessories: Verify options like oil separators, filters, and compatibility with base‑mount installations. Some models include integrated components that simplify setup.
When evaluating options for a small workspace, prioritize reliability, ease of maintenance, and compatibility with your power sources. The models listed here provide a spectrum of capacities and configurations designed to fit compact environments while delivering dependable compressed air for diverse tasks. Always confirm electrical compatibility and space constraints before purchase to ensure seamless integration into your shop or facility.
