Airflow controllers

Airflow controllers

Airflow controllers are designed for constant (CAV) or variable (VAV) airflow volume control in circular or four-sided HVAC ducts. Thanks to the regulation of air flow volume or duct pressure, the use of variable or constant air flow volume controllers is more economical for the operation of the HVAC systems. We supply air flow controllers for circular and four-sided ducts, from manually operated to electrically adjustable by servo drives.

DIRU

DIRU

The DIRU regulating dampers with air flow meter are used for regulation and measurement of air flow in circular ducts. The DIRU dampers are characterized by low noise level, class C air-tightness and the possibility of full opening for duct cleaning. The DIRU air flow regulators are made of galvanized sheet steel and are supplied with a control mechanism, measuring scale and pressure gauge connections. The dampers are connected to the ducts by means of rivets or self-tapping screws. The connections are equipped with a double-lipped EPDM rubber seal and are therefore widely used in projects with special tightness requirements.

 

IRIS

IRIS

The IRIS regulating dampers with air flow meter are an ideal device for regulating and measuring air flow in circular ducts. The IRIS dampers are characterized by low noise level, the possibility of full opening for duct cleaning and by a very tight construction.

RDR

RDR

The RDR constant air flow volume controllers are used for precise mechanical adjustment of the required air volume in the pressure range of 50-250 Pa. The RDR controllers are used in HVAC systems for both air inlet and outlet. The air flows through an opening inside the controllers in which the damper changes position according to the specified air flow volume. The built-in damper is connected to a calibrated spring and therefore no additional drive is required. The damper can be adjusted using a locking screw. The air flow volume change is only possible within the range of the controllers specified in the product code. The RDR are made of grey plastic material (polystyrene) classified as M1. Operating air temperature range is from +5 to + 60 °C.

The maximum ambient temperature is 70 °C.

 

SPM

SPM

The SPM is an iris damper for air flow volume control. The SPM has a central sealing element with higher throttling effect. It is designed to control and measure the air flow volume and has higher throttling capacity thanks to a central foam rubber sealing element. Low noise level (no silencer needed behind the controller), uniform airflow, with centric circular cross-section, precision measuring accessories.
