Maintaining Commercial Sprayfoam Equipment

From transfer pumps and spray guns to hoses and compressors, there is no question that the quality of any Spray Polyurethane Foam (SPF) insulation job is dependent on well-functioning commercial sprayfoam equipment.

While some contractors may view it as a time-consuming task, carrying out regular maintenance on your commercial spray foam equipment is well-worth the effort if you want to get a job done the right way, the first time around.

Below, the Intech Equipment & Supply customer support team has compiled a list of our top suggested maintenance tips for your commercial sprayfoam equipment:

Power-Related Pieces

  • Commercial sprayfoam equipment requires electricity and compressed air. Make sure your air and power supply can generate adequate pressure to drive your equipment. We suggest confirming that the air is clean and dry; otherwise, you risk a poor mix.
  • Check your power supply going to your sprayfoam machine with an amp clamp meter daily. This simple operation can easily prevent issues resulting from inconsistent power.
  • Confirm the voltage going to the spray foam machine, and compare it with the required voltage suggested by the equipment’s manufacturer. If the voltage is too low, it can result in heat issues and, in some cases, harm the motor.
  • If you are using a generator, make sure it does not run out of fuel while the machine is in use. The majority of commercial sprayfoam equipment manufacturers feature lights on their machines to display when power is correct.
  • When power is off on your machines, check plugs, switches, and coils for any loose connections.

Proportioning Pump

  • A proportioning pump has two main responsibilities: pressure and ratio. If you believe a larger-than-normal size particle has found its way into your pump, unfortunately, it can lead to problems. To prevent this scenario, always check the Y-strainers when introducing any new material.
  • SPF preparations require exact pressure and temperature to react in order to provide maximum yield. The drive system connected to pumps of equivalent volume, creates pressure and pushes the chemicals through a swift heating system. To avoid issues, it is critical to inspect the filter, check the hydraulic oil level, and change the hydraulic oil when the manufacturer’s suggested time occurs.

Heated Hoses and Spray Guns

  • The sprayfoam gun is where “all of the magic” happens. This magic involves mixing two components at precise ratio, pressure, and temperature levels. Most spray guns are air purge, which means there is an airstream exiting the gun nozzle when it is not spraying foam. To keep your spray gun in top shape, leave this element “on” during normal operation and be sure to check for condensation.
  • Inspect and clean the filter screens in your spray gun every day, or when material pressures are off-balance. Treat your spray gun’s exterior with silicon mold release to ward off material buildup and make cleaning simple.
  • Your commercial sprayfoam equipment’s heated hose system can often take the most abuse. Heated hoses are commonly hauled across job sites, up walls, around corners, and through constricted spaces. Before each new job, take the entire hose off its vertical hanging rack before turning on the heat. If you do not take this step, you can place undue stress on the hose length on the frame supporting the weight of the bundle, and it can lead to damage.
