Dramm FM50 Foamer Replacement Parts
About this product
Replacement components for the Dramm FM50 Foamer, a cart-mounted, air-operated foaming machine that produces a rich, aerated, shaving-cream-like foam for the application of disinfectants, sanitizers, and cleaning agents in greenhouse, nursery, and food-production environments. Unlike siphon-based or hose-end foamers that generate thin suds, the FM50 injects externally supplied compressed air into the spray solution at the nozzle, producing a dense foam that clings to vertical and overhead surfaces and degrades slowly to extend chemical contact time. These parts cover the pressure-regulation and flow-control elements of the foaming circuit.
Replacement Components
| Component | Function | Connection |
|---|---|---|
| Pressure Regulator Kit | Regulates incoming compressed-air pressure to the foamer's operating specification and stabilizes foam quality. Includes fittings and a tee installed on the pressure output ahead of the discharge hose. | Inline, pressure output |
| Needle Valve with Nut | Provides fine metering of flow through the foaming circuit, controlling the air-to-solution ratio that determines foam density and persistence. | 1/4-Inch PTF (dryseal pipe thread) |
| Panel Nut Needle Valve | Panel-mounted needle valve for flow adjustment accessible at the unit's control panel. | Panel mount |
System Operating Specifications (FM50)
- Air requirement: 60 PSI at 5 CFM (cubic feet per minute) from an external compressor (not included)
- Foam throw: up to 15 feet
- Tank: 50-gallon polyethylene, mounted on a vinyl-dipped HydraCart frame for resistance to harsh detergents and corrosive chemicals
- Standard hose: 25 feet EPDM rubber; expandable up to 75 feet with sufficient compressor volume
Functional Mechanism
The pressure regulator establishes a stable working pressure from the compressed-air supply. The needle valves then meter the proportion of compressed air blended with the spray solution, allowing the operator to tune foam richness and dwell time. Because foam created with compressed air is denser and longer-lasting than atmospheric or siphon-generated suds, it adheres to walls, benches, and structural surfaces, increasing the disinfectant contact time required for effective sanitation.
Compatibility
For use with the Dramm FM50 Foamer. The FM-series foaming system is shared across the FM20 and FM50 units; verify the specific valve threading and regulator configuration against the unit being serviced.
