Air Treatment Maintenance Kits

Air dryer maintenance kits typically include filter elements, desiccant recharge media for desiccant dryers, inlet and outlet valve seals, refrigerant gaskets for refrigerated dryers, and drain valve service components. Kits are model-specific and bundle the parts required for the manufacturer specified scheduled service interval, ensuring no critical service components are overlooked during maintenance.

Refrigerated air dryers typically require filter changes every 6 to 12 months or at 3,000 to 4,000 hours of operation. Desiccant dryers require desiccant bed replacement every 1 to 3 years depending on inlet conditions and duty cycle. Coalescing filter elements downstream of dryers should be changed at least annually in most shop environments.

Skipping maintenance causes filter elements to become saturated and bypass, allowing moisture and oil to pass through to downstream tools and processes. Clogged elements increase pressure drop across the treatment train, reducing available system pressure at the tools. In desiccant dryers, exhausted desiccant loses dew point performance entirely, allowing moisture breakthrough to sensitive equipment.

Yes. Maintenance kits are model-specific — each kit is engineered for a specific model's service interval and component specifications. Using a generic or wrong-model kit can result in incorrect element sizing, seal mismatches, or desiccant volume errors. Always confirm the model number before ordering a maintenance kit from Alamo Equipment.

Manufacturers recommend OEM maintenance kits to maintain warranty coverage and ensure proper fit and performance. Third-party kits may fit physically but can use lower-efficiency filter media or incorrect element ratings. For equipment under warranty, OEM kits are required to preserve warranty terms. Alamo Equipment stocks OEM maintenance kits for FS Curtis treatment lines.

Locate your unit's model number from the nameplate or documentation. Provide the model number to Alamo Equipment and specify the service interval — first service, annual, or full overhaul. The model number determines which kit applies. Alamo Equipment's parts team can cross-reference the model number to the correct kit part number quickly.

Yes. Oil-water separator maintenance kits include replacement filter elements and bowl seals. Oil-water separators should be serviced at least annually and whenever the sight glass shows high oil accumulation. Ignoring separator service allows oil-contaminated condensate to discharge to floor drain — a regulatory issue in most jurisdictions requiring separate oil-water disposal compliance.
