Compact vehicle and light commercial applications
The A-900 is the compact-enclosure unit for large-displacement passenger vehicles, 4WDs and light commercial duty. For heavy commercial transport, continuous-duty service and generator-set installations, specify the H-900 — same 900 ml/min output in an industrial cabinet.
- ▸Large passenger vehicles, 4WDs & vans
- ▸Light commercial duty cycles
- ▸2.7 – 7.0 L gasoline & diesel engines
- ▸Compact engine-bay / behind-cab mounting
Compact vehicle and light commercial duty. Large passenger vehicles, 4WDs and light commercial up to 7.0 L in the compact engine-bay enclosure.
Same 900 ml/min output in an industrial cabinet. Recommended for 20 – 30 kW generator sets and heavy commercial transport — vibration-isolated, behind-cab / pad-mount, onboard ion-exchange polisher, continuous-duty packaging.

Manufacturer test data reports selected fuel-consumption reductions in the 15 – 20% range, reduced carbon accumulation and smoke, and improved combustion stability. Actual results vary materially with engine condition, duty cycle, load profile, fuel quality, installation and operating conditions. Field evaluation is required before commercial projection.
