Reduce that Pressure Part #1

Reduce that Pressure Part #1

Posted by Andrew Greess on Nov 25, 2014

Without pressure, most power and manual pest control sprayers won't work. The problem is too much pressure, which has a number of negative impacts, including decreased sprayer life.

Here is an interesting observation. When we build a new gas-powered pest spray rig, we set it at about 75 PSI. When spray rigs come into our shop for service, they are often set at 150 PSI or higher.

The pressure isn't magically increased by a pressure fairy. Pest control technicians turn up the pressure to finish their jobs faster.  Here are some of the consequences of running a power sprayer at higher pressures: 200-Gallon-Fiberglass_QSpray

  • igher operating pressure reduces the life of pump, hoses, fittings, o-rings, seals, gaskets, etc.
  • Chemical spills will be larger and more serious when a component bursts at higher (rather than lower) pressure
  • Higher pressure can also affect spray droplet size, which can cause unintended consequences such as spray drift.  Can you say “lawsuit”?
