Description

The Sealey SA77 is a 150mm random orbital air disc sander designed for professional finishing and surface preparation work. Built with a lightweight aluminium body at just 1.55kg, this pneumatic sander features a double bearing counter balance assembly that minimises vibration and fatigue during extended use. The balanced design incorporates a composite cap and internal baffle system that reduces operational noise to 87dB(A), making it more comfortable for prolonged sanding tasks in workshop environments. A spindle lock device enables quick and easy pad changes, whilst the integrated airflow control valve allows precise adjustment of sanding speed to suit different materials and applications. Operating at 90psi with a free speed of 10,000rpm and a 4.2mm orbit, this air sander delivers consistent material removal across metal, wood, plastics, and composite surfaces. The tool comes supplied with a 150mm hook-and-loop backing pad that accepts standard abrasive discs, providing versatility for panel preparation, filler work, primer flatting, and final finishing operations. With an air consumption of just 4cfm and a standard 1/4"BSP inlet, the SA77 is compatible with most workshop compressor setups.
