Powerful Cutting Coupled with Brake System


CS Unitec offers a complete line of pneumatic chain saws for cutting wood and plastic, as well as for underwater and underground applications. Series 5 1026, 5 1027, 5 1028 and 5 1029 air saws are designed with a chain brake to stop chain movement during kickback or repositioning of the saw during cutting. This is a unique safety feature that is required by many industries. These heavy-duty air chain saws feature two separate oil lubricating systems. One oiler provides lubrication to the saw chain. A separate oiler automatically lubricates the motor for long life, easy startup and low-maintenance.


Safer than gas or electric in hazardous atmospheres, these pneumatic saws are suitable for use in hot work areas, Ex zones or hazardous environments. The powerful 4 HP motor consumes 92 CFM of air at 90 PSI. Each series of saws is available with a cutting capacity of 15”, 17”, 21” or 25”. Standard equipment includes an Armor Tipped Guide Bar and a Super Chisel saw chain 404 pitch. Carbide-tipped and ripping saw chains are also available for special cutting applications. The carbide tipped saw chain will cut through steel nails, creosoted wood and wood with barnacles underwater. 


The Series 5 1026 air chain saw is optimal for cutting wood. It is used for heavy-duty applications by construction, power generation utilities and municipal rail transit systems. Series 5 1027 plastic-cutting chain saws come with integrated water feed to lubricate the saw chain. This is ideal for use in cutting polyethylene and plastics in the petrochemical, oil and process industries. Series 5 1028 is ideal for underwater use especially to cut wood pilings around docks and shipyards.  Series 5 1029 is engineered for safe operation in mining and underground applications. Many air saw models in the aforementioned lines are ATEX Classified for working in Ex Zones.
