Frequently asked questions

Common questions about PROSTOCK from 3G Electric.

What refrigerants are PROSTOCK scroll compressors compatible with?

PROSTOCK scroll compressors are designed for use with R-410A refrigerant. This is a common HFC blend used in modern residential and light commercial air conditioning and heat pump systems. The compressors are hermetic, meaning the motor and compressor are sealed within a single housing, which prevents refrigerant leakage and contamination. Always verify the specific model's compatibility with your system's refrigerant type before installation.

Are PROSTOCK blower wheels direct replacements for Rheem equipment?

Yes, PROSTOCK dual-inlet forward-curved blower wheels are listed as compatible with Rheem-branded air handlers and furnaces. The wheels feature aluminum/steel construction, clockwise hub-end rotation, and specific diameter and width dimensions (e.g., 11 15/16 inches diameter, 8 1/16 inches width) that match Rheem OEM part numbers such as PD703027 and 703015. Always cross-reference the manufacturer part number with your existing wheel to confirm fit.

What is the cooling capacity range of PROSTOCK scroll compressors?

PROSTOCK scroll compressors are available in cooling capacities from 25,100 BtuH to 52,100 BtuH. For example, model 55-102045-185 provides 25,100 BtuH, while model 55-107225-189 delivers 52,100 BtuH. All models use a 1/2-inch discharge line connection and are hermetic scroll type. Select the capacity based on your system's tonnage and load requirements.

What materials are used in PROSTOCK blower wheels?

PROSTOCK dual-inlet forward-curved blower wheels are constructed with an aluminum wheel and steel hub. The aluminum wheel provides corrosion resistance and lightweight operation, while the steel hub ensures durability and secure mounting. This combination is standard for HVAC blower applications requiring quiet, efficient airflow.

Can PROSTOCK fan blades be used in condenser units?

Yes, PROSTOCK propeller fan blades, such as the 24-inch diameter, 22-degree pitch, three-blade model (MPN 70-101323-58), are suitable for use in condenser fans and evaporator coils. The blade has a 1/2-inch bore diameter and is designed for axial airflow in outdoor condensing units. Verify the bore size and pitch match your fan motor and shroud specifications.
