FS-Curtis Belt Guard
FS-Curtis belt guard replacements and service parts — full and partial belt guards for reciprocating piston compressor configurations. Belt guards are OSHA-required safety covers that protect technicians from rotating pulleys and belts during compressor operation. This collection covers OEM replacement guards matched to specific FS-Curtis compressor models. Operating a compressor without the belt guard installed is an OSHA citation hazard. Alamo Equipment is an authorized FS-Curtis dealer with parts availability nationwide.
FS-Curtis Belt Guard FAQs
It is an aftercooler that mounts in the belt guard position on a reciprocating compressor, using the existing flywheel airflow to cool the compressed air. It adds aftercooling without needing a separate cooler with its own footprint and fan.
Compressed air leaves the pump hot and fully saturated. An aftercooler drops that temperature so a large share of the moisture condenses out at the compressor rather than downstream in the shop piping. Without one, the water ends up in your air lines and tools.
These are matched to specific pump models — the collection lists them by the pump models they fit, such as C98, D96 and C79, or D97 and C89. Identify your pump model, then select the matching belt guard aftercooler. They are not universal.
No. An aftercooler removes the bulk of the moisture by cooling; a refrigerated dryer takes the air down to a controlled dew point. They work together — the aftercooler reduces the load on the dryer so the dryer can hit its rating.
That is the normal use case. It replaces or integrates with the existing belt guard on a compatible pump. Confirm the fit against your specific pump model, and confirm the installation maintains proper guarding of the belt drive.
It reduces discharge air temperature and moisture content without changing the compressor's rated output. The practical effect is far less water carried into the shop piping, which means fewer problems at the tools and less load on any dryer downstream. It does not increase or decrease the CFM the unit delivers.
The unit is designed to serve the belt guard position, and belt drives must remain properly guarded for safe operation. Confirm on installation that the drive is fully enclosed as required, and do not run the compressor with any portion of the drive exposed while waiting on parts.
