Choose either the 5 hp Briggs & Stratton engine for up to 4130 cfm output or the 8 hp Tecumseh engine for 8761 cfm. Throttle control lets you vary the cfm output. These blowers feature a durable 30" diameter base with a heavy duty neoprene seal. The Ripcord Blower has 18-1/2" ID and the Super Ripcord has a 23-1/2" ID (for part of blower that fits into the manhole).
The liquid smoke blowers are a more cost effective way of smoke testing. One gallon of liquid smoke can last up to an hour. Conversion kits are available to modify your existing blower.
The Blow-In Ventilation Kit includes a fiberglass cowl, sturdy steel folding stand, and 20' of heavy-duty vent hose.
