Needle Scalers


CS Unitec has introduced a line of low-vibration needle scalers with a dust shroud designed for all surfaces – metal and masonry – to remove coatings, corrosion and other accumulated materials. These tools are ideal for irregular surfaces that are otherwise difficult to prepare. The Trelawny™ Vibro-Lo™ VL Series of scalers are lightweight, easy-to-handle pneumatic units that provide up to 3000 blows per minute with 1/7 the vibration of traditional needle scalers. Other applications include chipping, weld dressing and brick/stone cleaning. 

The dust shroud maintains worksite / environment cleanliness when the tool is attached to a vacuum system. The Vibro-Lo™ VL Series includes 3 models: The VL223-139.2103 inline model is equipped with 19 needles. Models VL203-139.2003 and VL303-139-3003 are designed with a pistol grip and have 19 and 28 needles, respectively. Changing needles is quick and easy, requiring no additional tools. Needle variations include chisels or flat for light surface marking and pointed needles for very hard scale removal. Non-sparking Copper Beryllium needles are available for use in potentially hazardous environments. Stainless steel needles are offered for applications where corrosion or humidity presents a problem. 

The scalers operate at only 5.5 CFM of air with vibration levels up to 2.3 Aeq m/s2.
