Unifire 20" Univent Pro-Saw Ventilation
Unifire 20" Univent Pro-Saw Ventilation
ET Series Engine (Extreme Torque)
High performance engine reduces fuel consumption up to 20% and emissions up to 60%. The saw produces up to 20% more horsepower than stock increasing torque over a wider RPM range when ventilating a roof or cutting/felling trees. The ET Series gives more power throughout the cut.
Ram Jet, Forced Air Injection
The specially designed flywheel removes 97% of debris from the air with centrifugal force and provides 35% more airflow around the engine than standard flywheels. The clean air is channeled to the carburetor housing, pressurizing it through force injection. The end result is higher performance, better air filtration, and a longer lasting and cooler running saw.
Superior Air Filtration Technology
The ventilation series saws combine the Ram Jet, Forced Air Injection System with a pure foam air filter, allowing 300% more airflow for heavy smoke and low oxygen environments. A pure foam air filter will not plug up in heavy smoke like paper or nylon filters.
Two Mass System
Ergonomically designed handles with, optimum spacing and an anti-vibration system minimize fatigue and provide an unsurpassed operator experience. The two-mass system isolates the saw's handles from the engine and cutting arm with steel springs, minimizing vibration transferred back to the operator. The weight of the saw is balanced evenly between the two handles.
All position Vortec-Excelerator Carburetor with ported and polished dual charged transfer ports and Vortec-Excelerator chambers. Built in auto-filter compensating system, provides extreme power and engine acceleration with low emissions and excellent fuel economy. This specialty unit is mounted using vibration-dampening system that is designed to prevent vapor locking in extreme heat situations.
Easy-Start Compression Relief Valve
The engine and starter have been designed for quick starts with minimal effort. Resistance in the starter cord is reduced by up to 40%. With the Easy-Start Compression Relief Valve, simply push the button, pull the cord, and as soon as the saw fires it is automatically reset to full compression.
Molytech Cylinder Head
Molybdenum impregnated and hardened aluminum/magnesium cylinder head with drop forged 74cc piston and moly-rings, increases compression, reduces heat and extends engine life. Allows the engine to run fuel with up to 15% alcohol content. This allows optimum performance from standard 87 to 92 octane fuels. Alcohol is added to standard fuel in order to meet emission standards set by the EPA and other city or state ordinances. Emission standards will vary depending on where you live. Alcohol burns three times hotter than gasoline.
A proper gas and oil mix of 50:1 is recommended.
Exclusive Rescue Chain Technology
Exclusive to Unifire with over twenty-three years in the design and engineering, this chain can out-cut and out-perform any other chain on the market, period! We guarantee it. If you want safety, speed and durability, look no further. In hundreds of head to head tests, this chain won every time.
- Manufactured exclusively for Unifire and Univent by Carbide Chain of America.
Eliminator - Air Purge
The Eliminator air purge system removes air from the fuel lines, allows for faster starting and better performance. Fuel lines are alcohol resistant.
Hyper-Volt : Electronic Ignition
The smart brain of the Hyper-Volt electronic ignition senses when the saw is under load and advances the voltage to maintain higher performance through the cut.
