Inlet Filter The intake filters are designed to ensure maximum airflow efficiency why keeping out unwanted debris. The filters supplied by NVE use a stainless steel screen and can be cleaned. www.natvac.com | 800.253.5500... -
Page 19: Four Way Valve And Hoses
If the blower is intended to be used in pressure mode then a pressure relief valve is required. NVE recommends the use of Kunkle pressure relief valves as they have been proven to work well and have sufficient flow capacity. The valves we supply are factory set to 10 PSI and are sealed. -
Page 20: Secondary Shutoff/Moisture Trap
Secondary Shutoff/Moisture Trap The secondary shutoff or Moisture Trap should also be appropriately sized for the air flow application. Contact NVE for assistance with selecting the shutoff. Bag House Bag houses are typically used in systems where dry material is being pumped. Spec- ification of a proper bag house depends on the frequency and type of dry material being pumped. -
Page 21: Operating
Before starting blower, verify the shaft rotates freely by hand. Water can con- dense and freeze in the blower cylinder without warning causing a stall condition at start up. www.natvac.com | 800.253.5500 4307 & 4310 Blower | 21... -
