THE DIAMOND BLADE CONCRETE CUTTING CHAINSAWS ARE AVAILABLE IN 12, 14 OR 16 INCH MODELS.

Both of these units are based on the tough and reliable Husqvarna chainsaw professional power units which are extensively modified by Unifire in the USA specifically for demanding use by Rescue Services.

The Unifire Univent rescue and tactical ventilation chainsaws have the options of Sabretooth and Cobra carbide tipped chains which are ideal for tough cutting tasks in harsh environments, they have also been used by Police and Prison Services for MOE purposes.


The chainsaws are fitted with unifire's unique (patented) depth/plunge gauge which both assists the operator during use and provides added control and high degree of protection for the operator and casualties.

These saws can cut through a wide variety of building materials including  steel sheet cladding on panels and doors, composite insulated roofing sheets with foam or rockwool filling, sandwich panels, glass and double glazed units, aluminium, plastics and wood.


Unifire High Performance Ventilation Rescue Chainsaws
A chainsaw engineered specifically for the fire and rescue industry, these saws have a number of features that make them outstanding tools for the fire and rescue industry. No matter what you are cutting, Unifre have a high performance rescue saw, blade, or chain that will do the job.

Univent Saws are designed to prevent vapour locking in high heat situations and are air injected with a pure foam air cleaner that is impossible to plug - even in a heavy concentration of smoke.

These saws develop over 6 HP and reach chain speeds of 121.6 ft. per second. This allows the chain to use a filing action rather than ripping and tearing, perfect for the harsh environments of the Fire Service.

Unifire Ventilation Saw Features
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 channelled to the carburettor 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.

Vortec-Excelerator Carburettor All position Vortec-Excelerator Carburettor 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 vapour 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 aluminium/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.

Unifire offfer both the Sabretooth and Cobra chains FOR THE UNIVENT VENTILATION/RESCUE SAW, THESE are 'patent protected' and are unique to Unifire, they are based on Oregon chains which are modified by carbide chain of America specifically for the task.
Both carbide chains feature the same high quality, C-11 carbide teeth with 575,000 PSI, transverse rupture strength.
Both chains feature 1,800° F silver solder and the heaviest chassis available to a chain this size.
The difference lies only in the number of teeth, the Sabretooth Carbide Chain features teeth with one space with  an anti-kickback safety link instead.
This chain is designed for use on standard building materials AND PROVIDES A FASTER CUT ON

TIMBER COMPARED TO THE COBRA.


The Cobra Carbide Chain features a little different design.
Instead of having a space with a safety-link, the Cobra has a tooth on each link. This tooth allows the chain to last twice as long and cut through harder Materials, i.e. THOSE ENCOUNTERED IN COMMERCIAL AND INDUSTRIAL STRUCTURES.
