Sprinkler Blowout Pressure vs Airflow: The Difference

Sprinkler blowout pressure vs airflow: check the limits

Hunter separates airflow needs from pressure limits and says the lowest-rated component must be respected. A published maximum is not a target for every system. The contractor needs to identify the installed parts and their condition before deciding on the method. A compressor label alone cannot answer that question.

Ask about the irrigation equipment too

Useful questions include which parts need separate handling and how the service connection is identified. A photo of the compressor tank does not explain either one. If you have unfamiliar equipment, gather its model details for the technician rather than trying different connections or settings yourself.

Keep preparation simple and safe

Have the zone list, access arrangements and equipment records ready. Do not run a trial with stored compressed air to see what happens. This guide explains terms you may hear when booking; it does not provide an operating sequence. Leave uncertain specifications and connections to a qualified professional.
