Metal & Machining

When it comes to metal fabrication and machining, the equipment’s surrounding ambience during operation is key. Dry, clean and oil-free air environment is paramount to metal fabrication as a guarantee of precision, quality and cost-effectiveness. Whether it is forging, laser, plasma cutting or engraving, our customers choose us to upgrade their process and cut costs.

Under the broad term machining, we cluster the need for precise air control to deliver optimal performance and longer equipment lifetime. Our air filter equipment exceeds expectations by checking all the boxes while lowering CO2 emissions, protecting worker’s health and warranting compliance to existing rules and legislation.

Our range of durable filters safeguard the reliability of industrial equipment and prolong service life while dramatically reducing overall operational costs.
