A way to clean out a wall-hung split air conditioning system without removal. No more dragging hoses or tearing out coils for cleaning. The CoilJet from SpeedClean brings water, power and 125 psi of pressure with it, in a compact and portable design for on-the-go HVAC coil cleaning.
Specifically designed for condenser coil cleaning and evaporator coil cleaning, the CoilJet replaces a powerful pressure washer — and the not powerful enough hand pump sprayer — to quickly clean coils without damage to sensitive fins, even microchannel coils. The CoilJet produces 125 psi of coil washing power at about 2.2 litres per minute water flow that won't overwhelm condensate lines inside. This means you don't have to pull the evaporator coils out to clean the coils.
The Deluxe Package combines the standard SpeedClean CoilJet CJ-125 with a split bib kit, accessories and chemicals, for technicians setting up to service wall-hung split systems.
Speed Clean CoilJet Deluxe Kit includes
- CoilJet CJ-125 portable coil cleaner with standard spray gun attachment
- 12 V deep cycle rechargeable battery plus smart battery charger
- 2 spray nozzles — 15° for coil cleaning and pinpoint for condensation tray clean-up
- 20 ft self-coiling hose
- Heavy duty shoulder strap
- CoilJet CJ-125 user manual
- Split bib kit (see below)
- Accessories and chemicals
The specific accessories and chemicals in the package are not itemised on file. Contact us for the current contents before ordering if a particular item matters to you.
Split bib kit
Clean split coils, fan blades and more without making a mess.
- Allows quick and easy cleaning of coils, fan blades and more
- 3-metre hose funnels all coil cleaner and water safely into a container of your choice for easy transport and disposal
- Keeps walls and surroundings safe from water and cleaner spray
The system is simple to use. Hang the bag underneath the indoor unit, and the chemicals, water and debris drain into your container without mess.
Note: CCW's package listing gives a 3-metre hose; SpeedClean lists an 8 ft (about 2.4 m) hose on its standard MSB-KIT bib kit. The kit sold separately is the SpeedClean Mini-Split Bib Kit.

Chemical dilution — valve setting
The chemical valve meters concentrate into the water stream. SpeedClean's settings (counter-clockwise to open):
| Chemical valve | Dilution (water : chemical) |
|---|---|
| 1 turn open | 30:1 |
| 2 turns open | 20:1 |
| 2.5 turns open | 10:1 |
| 3 turns open | 6:1 |
| Fully open | 4:1 |
Set the valve to the dilution on your coil cleaner's label, not the strongest setting.
Important — chemical compatibility
SpeedClean's manual says not to use acids or cleaners containing sodium hydroxide or potassium hydroxide in the CoilJet, and not to mix chemicals. The machine is designed for non-caustic alkaline coil cleaners; caustic products pit and degrade internal parts, especially if left standing. If a harsh cleaner has been used, flush the chemical tank, valve and pump with clean water straight away. Check the SDS of any cleaner before it goes in the tank, and ask SpeedClean or CCW if in doubt.
Operating the CoilJet (SpeedClean manual)
- Fill the water and chemical tanks. Close the chemical valve fully and remove the nozzle from the gun.
- Switch on and squeeze the trigger to prime the pump. If it will not prime, fill both tanks, stand the unit on a support and hold the gun below the pump until a steady flow appears.
- Open the chemical valve fully and trigger until chemical comes through, then set the valve to the dilution you need.
- Fit the nozzle and apply the solution evenly to the coil.
- Close the chemical valve. Let a foaming cleaner sit for about 5 minutes if possible.
- Rinse the coil with clean water.
- Switch off and relieve the pressure by squeezing the trigger in a safe direction.
The pump stops when the trigger is released, but the system stays pressurised while the switch is on. SpeedClean says not to leave it in auto shut-off for more than 10 minutes.
Choosing a nozzle
- Yellow 15 degree: the coil cleaning and rinsing nozzle. Start here on evaporators and any aluminium fin.
- Red pinpoint: SpeedClean supplies it for condensate tray clean-up. Keep it off delicate fins.
Care and storage
- Run clean water through the pump at the end of every job, and charge the battery after every use.
- Do not run the pump dry, spray the unit itself, or use water hotter than 60 °C.
- For storage longer than a week, drain both tanks and flush the pump and chemical valve with clean water. Keep the battery on its smart charger.
- After long storage a pump diaphragm can dry out: SpeedClean suggests filling the unit and letting it sit for 48 hours before calling for service.
Troubleshooting (SpeedClean)
| Symptom | Check |
|---|---|
| Erratic pressure | Worn or clogged nozzle, low water or chemical, air in the pump (re-prime without a nozzle), clogged cap vent, water too hot, low battery |
| Motor runs with trigger released | Leak at the gun or pump, air in the system, empty tank |
| Motor stops abruptly | Flat battery, battery wires disconnected, switch off, thermal breaker tripped (switch off and let it cool) |
| Will not power on | Battery under 11 V, blown 15 A fuse in the base, loose or chemical-damaged wiring, charger output under 12 V |
| Chemical not mixing | Empty chemical tank, blockage at the tank outlet, stripped or caustic-damaged chemical valve |
Why clean split systems in place
Indoor air quality matters in the places people live and work, and a clean system is part of it. A coil and blower wheel washed in place restore airflow, and a system moving air freely generally runs more efficiently than a fouled one. The package gives you the tools to maintain split systems quickly, efficiently and effectively.

Frequently asked questions
What is the difference between this and the standard CJ-125?
The machine is the same. The Deluxe Package adds a split bib kit, accessories and chemicals.
Which chemicals are safe in the CoilJet?
Non-caustic alkaline coil cleaners. SpeedClean says no acids and nothing containing sodium or potassium hydroxide.
Will the bib fit my unit?
SpeedClean's standard bib kit suits wall-mounted units up to 44 in (about 1,118 mm) wide. Tell us the unit if you are unsure.
Does it need mains power or a tap on site?
No. The CoilJet carries its own water and runs from its 12 V battery.
Tell us the systems you service and we will confirm the current package contents, or help you choose between the Deluxe Package and the standard CoilJet CJ-125.
