RH31M-2DK.31.1R 133081 supports air-conditioning systems as a centrifugal fan, with 400 VAC listed in the supplied data. Its representative supplied feature is a 310 mm size specified in the upload data. Selection focus: acoustic limit during final model confirmation. Check the exact variant before ordering.
For HVAC and ventilation systems, the ZIEHL-ABEGG RH31M-2DK.31.1R 133081 provides a practical AC centrifugal fan platform. Its construction is intended for repeatable installation where cooling performance affects equipment availability.
The aluminum backward-curved wheel is integrated with an external-rotor motor in a compact single-inlet arrangement. Its geometry supports free-running use or integration with a suitable scroll, giving equipment designers flexibility when balancing airflow, pressure and installation space.
System qualification for RH31M-2DK.31.1R 133081 should use the final grille, nozzle and surrounding equipment structure. This helps manufacturers preserve useful airflow, manage sound and define compatible replacements.
This application gives designers a practical route to balance cooling demand, space and maintainability. For equipment serving HVAC, outdoor air-conditioning and ventilation equipment, ZIEHL-ABEGG RH31M-2DK.31.1R 133081 maintains planned air exchange through air-handling and outdoor HVAC equipment.
For equipment serving commercial and industrial refrigeration systems, ZIEHL-ABEGG RH31M-2DK.31.1R 133081 supports condenser and equipment ventilation in refrigeration systems. This application gives designers a practical route to balance cooling demand, space and maintainability.
The result is a practical thermal-management option for engineering review, procurement and replacement planning. Rail vehicles and trackside equipment use RH31M-2DK.31.1R 133081 where the AC centrifugal fan maintains directed airflow through transportation equipment exposed to changing loads.
OEM designs for industrial drying and wood-processing equipment can use ZIEHL-ABEGG RH31M-2DK.31.1R 133081; the unit carries warm, moisture-laden air through industrial drying equipment. The equipment relies on forced airflow to supplement the limited cooling available from natural convection.
No guaranteed lead time is provided in the supplied sources. Confirm current stock, required quantity, production schedule, and shipping date with the supplier.
The supplied row does not include airflow, pressure, speed, power, or noise values. Request the exact performance curve before final selection.
It may be evaluated for high-reliability cooling using the supplied parameters, but duty cycle, redundancy, ambient limits, and protection must be confirmed at system level.
No airflow or pressure figure is supplied for this exact row. Request the matching performance curve before sizing the system.
Match the complete model code, voltage, dimensions, mounting arrangement, airflow direction, performance point, and control interface to the equipment.
The upload sheet marks the item as In Stock, but available quantity should be confirmed when the order is placed.
