Description
Rocky Series replacement head — GOM-075R-230
the Tech West GOM-075R-230 is the factory-original 3/4 HP, 230-volt replacement compressor head for the Tech West Rocky Series of dental air compressors. Built on the proven Gast 72R platform (also referenced as 71R650), this is the same head Tech West installs on the production line — not a remanufactured or aftermarket equivalent.
Key Features
- 3/4 HP, 230 V single-phase — direct, drop-in replacement.
- 6.5 CFM output — matches factory Rocky Series specifications.
- Oilless design — no oil to add, no oil mist into the equipment room.
- Smart-Start technology — capable of starting under load to extend service life.
- Quieter operation than equivalent rocking-piston aftermarket heads.
- Permanently lubricated bearings — zero scheduled maintenance.
- Ships at 26 lbs for fast freight.
Key Selling Points
- the fastest path to restore production when a Rocky Series head fails — no rebuild kit assembly, no risk of mismatched parts.
- Saves the $4,000-$6,000 cost of replacing the entire compressor when only one head is at fault.
- Identical CFM, voltage, and mounting pattern to the factory original — no plumbing changes required.
- In-stock for next-business-day shipping from authorized Tech West distributors.
- Backed by Tech West parts warranty (contact manufacturer or USDD for current term).
What Makes This Unique
This is a factory part, not a generic Gast replacement bought in bulk and re-labeled. the valve plates, cup material, bearings, and motor windings are the same specifications Tech West tests and ships from Fresno. for a dental practice that cannot afford a half-day of lost production, the time savings of a guaranteed-fit factory head versus a generic substitute is reason enough to specify the OEM part.
How It Compares
A generic Gast 72R Series head can be ordered cheaper, but the dental-grade Tech West GOM-075R-230 ships with valve specifications and a cup material specifically tuned for dental intermittent-duty cycles. Aftermarket rebuild kits typically deliver only 12-18 months of service in a dental compressor; this factory head delivers the full Rocky Series duty-cycle expectation.
