MTM HYDRO - Orifice for foam cannon
MTM Hydro Foam Cannon Orifice
MTM Hydro Foam Cannon orifices are intended to allow foam cannons to be used on a variety of machines with varying PSI and GPM.
These orifices (nozzles) will more accurately accommodate a machine requiring a larger or smaller orifice that is rated in flow ranges above 4 gallons per minute or below 2 gallons per minute. The goal is not to increase or decrease the pressure, but rather to match the recommended orifice size for your machine as closely as possible.
All MTM Hydro foam cannon models come with a 1.25mm (3.5mm) orifice installed.
When trying to determine the correct orifice size, use a nozzle selection chart with your machine's specifications in GPM and PSI.
You can also look on the side of the nozzles that came with your pressure washer for a number sequence.
On MTM QC nozzles, for example, you will see 25030 which translates to “25° spray with 3.0 orifice”. “If you were to see this footage, you would choose the 1.1mm nozzle (3.0 orifice) for your foam cannon as it more closely matches the required specification of your pressure washer.
