The Air Vac is a handy, ultra-compact electric-powered vacuum pump developed to quickly and easily bleed unwanted air bubbles from oil-filled shock absorbers and differentials. The main platform is fully CNC-machined from aluminum, and includes exchangeable shock/diff stands and transparent plastic cover. Air Vac includes strong and effective vacuum pump that is powered by 12V power supply or 7.2V battery (not included). It includes holders for shock absorbers and differential, 600mm connecting cable with gold-plated banana plugs and comes in a premium hard case for safe storage & transport. This high-quality premium device is fully produced and assembled by HUDY in Europe and it is available in 3 different sizes for 1/10 off-road and 1/8 on-road.
