Washdown Gun + Nozzle Selection — Quick Reference
Washdown guns + nozzles are the spray-control end of workshop + commercial + industrial washdown systems — concentrating water flow + pattern for parts cleaning + vehicle wash + facility hygiene. Selection by water pressure + flow rate + spray pattern.
| Washdown Gun Type | Best For | Pressure Range |
|---|---|---|
| Trigger Spray Gun (Brass / Plastic) | General workshop + garden + light commercial | 0-10 bar mains water |
| Heavy-Duty Industrial Spray Gun | Vehicle wash + workshop + agricultural | 0-20 bar |
| Adjustable Pattern Nozzle (Fan + Jet) | Variable spray — wide fan to concentrated jet | Per gun rating |
| Foam Lance + Cannon | Vehicle wash + chemical application — foaming | Pressure washer compatible |
| Pressure Washer Trigger Gun | High-pressure cleaning + commercial wash | 100-200 bar pressure washer |
| Stainless Steel Gun (Food + Chemical) | Hygiene-critical + chemical exposure | Per pressure rating |
| Hot Water Rated Gun | Steam + hot water washdown — food + manufacturing | Up to 80°C typical |
| Air Wash Gun (Solvent + Air Mix) | Parts cleaning + solvent application | Pneumatic-driven |
| Garden + Multi-Pattern Nozzles | Light commercial + facility | Mains water pressure |
Critical: Match gun pressure rating to water source — pressure washer trigger gun on mains water = wasted capability; trigger spray gun on pressure washer output = catastrophic failure. Stainless construction for food + chemical environments — brass body sufficient for general workshop. Brands: Retracta, Hansa, Speed Tools. Companion: water hose reels, cleaning chemicals, cleaning + janitorial.
Washdown Guns & Spray Nozzles
Washdown guns and spray nozzles are used to clean equipment, vehicles, machinery, and processing environments where high-volume water delivery is required. AIMS stocks Dixon, Tecpro, and Trax washdown products for connection to hose reels and water supply lines, covering heavy-duty industrial through to general-purpose applications.
Dixon Flow Boss Washdown Guns
The Dixon Flow Boss washdown gun is a heavy-duty design rated to 350 PSI, with 1/2" BSP thread connection. It is widely used in industrial, agricultural, and food processing washdown applications. Dixon also stocks replacement and maintenance accessories including the Flow Boss protective sleeve, grip sleeve kit, and shaft kit — allowing field repair and extension of gun service life without full replacement.
Dixon Spray Nozzles
Dixon offers a range of twist-style spray nozzles for hose reel connections: the hose reel twist nozzle in 3/4" thread with rubber gasket is designed for standard hose reel outlets. The Power Jet Twist Spray Nozzle and Viper Fire Spray Nozzle are available in 1" and 1-1/2" thread sizes for higher-volume or fire hose applications. The Power Spray nozzle in 3/4" BSP plastic suits lower-pressure garden and light washdown systems.
Tecpro & Trax
The Tecpro Low Flow Heavy Duty Washdown Gun is available in blue and red colour options and is suited to environments where reduced water consumption is a requirement without sacrificing cleaning performance. The Trax wash gun is a compact, general-purpose option for workshop and maintenance use.

People Also Ask — Washdown Guns and Nozzles
Q: What's the difference between a washdown gun and a standard spray gun?
Washdown guns are heavy-duty industrial water guns designed for sustained use at higher flow rates and pressures than domestic garden sprays — typical use in dairy, food processing, transport washing, and industrial maintenance. They have ergonomic triggers for extended use, robust seals to handle continuous water exposure, and adjustable spray patterns from jet to fan. Standard spray guns may handle the pressure but fatigue or fail under sustained industrial use.
Q: Can washdown guns handle hot water?
Most quality industrial washdown guns are rated for hot water — typical limit around 60-80 degrees C for general washdown service. For high-temperature steam or sanitising service, dedicated steam guns with appropriate seal materials and metal construction are needed. Check the manufacturer's temperature rating before using a standard gun on hot water for extended periods — overheating shortens seal life.
Q: What spray pattern works best for general cleaning?
Adjustable cone-to-jet nozzles handle the broadest range of cleaning tasks — wide cone for area wash, focused jet for stubborn dirt or hard-to-reach spots. Fan-pattern nozzles cover more area per pass and suit large floor or vehicle washing. Multi-pattern nozzles (cone/jet/fan/mist) cost more but reduce the need to swap nozzles for different cleaning tasks.
Q: What hose connection does my washdown gun need?
Most industrial washdown guns use 3/8 inch or 1/2 inch BSP threaded inlets, suiting common industrial water hose fittings. Quick-release couplings (camlock or claw type) speed connection and disconnection in busy washdown areas. Match the gun inlet thread to your hose fitting; adapters are available but add a potential leak point.
Q: How do I extend the life of a washdown gun?
Drain after use to prevent corrosion and freeze damage. Avoid dropping on hard floors — internal seals don't tolerate shock loads well. Use clean water; particulate contamination wears the seal seats and nozzle apertures. Periodically lubricate the trigger pivot and replace worn seals before they leak. Most quality washdown guns are designed for easy seal-kit replacement to extend service life.
