typical environments the room controls are set to a negative pressure with a range

The following summarizes the Protector I-S Hood installed with limit switches for
automatic Intelli-Sense Blower operation.

Hood that adjusts 3 speeds automatically based off sash position, has built-
in over-amperage adjustment to prevent overheating, provides simple
