Atlas Copco small portable air compressors are robust, well-made and have low running costs. A HardHat™ canopy is tough, really tough. It is designed to be highly impact resistant so it can shrug off dents and fractures. In a tough working environment, this really pays off. Where even the best-protected steel canopy compressors are going to get bashed and bettered, a HardHat™ will keep its good looks longer. No dents, no scratches and corrosion. No time and money consuming repair and repaint jobs.
