In a metal products workshop, plasma cutting, air tools and the assembly line all draw air, and demand differs widely between shifts. With an unsuitable fixed-speed unit, idle running at low load is often higher than expected.
Total air was sized from each station's simultaneous use; an electric unit with a receiver handles peaks, and grouped service parts allow in-house maintenance.
Lower power use at low load, and better cut edges thanks to stable pressure.
Some fixed-speed units were replaced by KayDrill DMT permanent-magnet variable-speed units that follow actual demand steplessly. Multi-layer acoustic canopies and isolation mounts cut room noise, and a dedicated controller monitors pressure and protects against over-pressure, over-temperature and phase faults.
DMT160-36/7 (permanent-magnet VSD)
Electric two-stage units with a control strategy set to the process air profile; multi-layer acoustic canopies reduce boundary noise.
DM250-34/20
An LG Series electric unit with enhanced intake filtration for wood dust, and a low-noise acoustic design suited to a workshop next to offices.
