The Vevor air assist pump kit is designed for laser cutters and engravers rated 20W and up, delivering adjustable airflow from 10 to 50 L/min for cleaner, more precise results. It helps blow away smoke and debris, reduce surface temperature, and protect the laser lens during operation. The steady airflow supports smoother cuts, less discoloration, and improved engraving quality. Its low-noise design with rubber shock pads helps reduce vibration for stable performance. The pump is built with an aluminum alloy body for durability and long-term use.
