Airman PDS185S vs PDS400S vs PDS375DP: Which to Choose

Three Workhorses, Three Different Jobs

Airman’s portable diesel compressors are a staple on Malaysian sites. The PDS185S, PDS400S and PDS375DP cover light, heavy and clean-air duties respectively.

Choosing well means matching air output and air quality to the task — see our CFM sizing guide first.

Airman PDS185S — The Everyday Unit

At around 185 CFM, the PDS185S runs one or two breakers comfortably. It is compact, easy to tow and economical on diesel.

Ideal for renovation, light demolition and single-drill work. Browse it in our product range.

Airman PDS400S — The Heavy Hitter

At roughly 400 CFM, the PDS400S powers multiple tools or larger rock drills at once. Choose it when one machine must feed a busy crew.

Airman PDS375DP — Clean, Dry Air

The PDS375DP delivers around 375 CFM and an integrated after-cooler, removing moisture from the air stream. That matters for sandblasting and air-tool longevity.

Side-by-Side Snapshot

• PDS185S: ~185 CFM — light work, lowest running cost
• PDS400S: ~400 CFM — heavy, multi-tool, big sites
• PDS375DP: ~375 CFM + after-cooler — dry air for blasting and finishing

When the After-Cooler Earns Its Keep

Humid Malaysian air carries moisture that rusts tools and ruins paint and blasting finishes. The PDS375DP’s after-cooler is worth it whenever air quality matters — learn more in our after-cooler guide.

Which Should You Pick?

Pick the PDS185S for everyday light jobs, the PDS400S for raw volume, and the PDS375DP when dry, clean air is the priority.

Match air quantity to your tools and air quality to your finish.
