Specification
Halton HMC is a manually operated cabin unit for single duct applications. The unit can be installed directly through one ceiling blade (300 mm). Airflow is controlled via an adjusting knob installed through the diffuser. The control mechanism has mechanical limits for minimum and maximum airflows. Airflow limits can be easily set during commissioning. HMC is recommended to be used in conjunction with Halton’s TCL diffuser that is specifically designed for HMC cabin unit.

Function
Airflow is controlled via an adjusting knob installed through the diffuser. The control mechanism has mechanical limits for minimum and maximum airflows.
Installation
HMC can be installed directly through one ceiling blade.
Adjustment
The supply flow rate is determined by using a handheld measurement device. Adjust the minimum airflow rate by rotating the D-shape bar until the desired setting is achieved. Move the minimum airflow mechanical limiter against the stand and tighten socket cap screw. Adjust the maximum airflow rate by rotating the D-shape bar until desired setting is achieved. Move the maximum airflow mechanical limiter against the stand and tighten socket cap screw.
