Compressed Air Parts

Alamo stocks replacement parts for FS Curtis lines — pump rebuild kits, valve plate assemblies, motor components, pressure switches, magnetic starters, air filter elements, oil filters, coalescing elements, separator cartridges, drain valves, and electrical service parts. Contact the Alamo parts desk to confirm current stock and the expected ship date for a specific part.

Yes, in most cases. FS Curtis, and other manufacturers warranty their equipment only when OEM parts are used during the warranty period. After-market parts may fit physically but will void warranty coverage if the manufacturer determines a non-OEM part contributed to a failure. Stay with OEM parts during the warranty window without exception.

Identify the compressor's model number and serial number from the data plate, then cross-reference against the manufacturer's parts diagram. FS Curtis publish parts manuals organized by serial-number breaks because revisions occur within a model run. Provide both numbers when ordering — Alamo's parts desk will confirm exact fitment before processing the order.

Reciprocating piston pumps typically need valve and ring service every 4,000 to 8,000 hours of operation depending on duty cycle and ambient conditions. Heavy-duty shop use at 50 percent duty cycle reaches this interval in roughly 2 to 4 years. Rotary screw airends follow scheduled service kits at fixed hour intervals defined by the manufacturer — do not extend these intervals.

Coalescing elements remove oil aerosols and ultra-fine moisture droplets from compressed air, sized in microns (typically 0.01 to 1 micron). Particulate elements remove solid contaminants like rust and pipe scale, sized larger (1 to 25 micron). A proper treatment train uses both in sequence: particulate first, coalescing downstream. Replacing the wrong element type degrades downstream air quality.

Most coalescing elements have a 12-month maximum service life regardless of differential pressure indicator readings — the media degrades with time even without heavy contaminant loading. Replace particulate elements when the differential pressure gauge climbs above the manufacturer's red zone, typically 7 to 10 PSI. Track install date with a service sticker on the housing.

Yes. Activated alumina and molecular sieve desiccant replacements are stocked for FS Curtis desiccant dryer lines. Desiccant typically lasts 3 to 5 years before needing recharge — sooner if oil contamination has saturated the bed. Replace immediately if outlet dew point begins climbing above specification.

Sometimes the physical port and electrical specs match across brands, but the cut-in and cut-out pressure ranges, differential settings, and unloader actuation differ. Always specify the original equipment manufacturer part or a verified cross-reference. A pressure switch with the wrong differential will short-cycle the compressor and shorten motor life significantly.

Shipping timing depends on current stock and fulfillment source. Less common parts and large pump assemblies may require additional lead time. Contact the Alamo parts desk to confirm current stock and the expected ship date for any specific part number before placing a time-critical order.
