About PLASTEC

PLASTEC is a manufacturer of corrosion-resistant blowers and air-moving equipment designed for hazardous-location and corrosive-atmosphere service. The product line is built around direct-drive blower configurations that combine a totally enclosed motor with a corrosion-resistant housing and wheel, allowing the units to operate in environments where combustible dusts, vapors, or aggressive chemical fumes are present. PLASTEC blowers are commonly specified in industrial ventilation, fume extraction, and process air applications across chemical processing, wastewater treatment, pharmaceutical manufacturing, and metal finishing operations.

The PLASTEC range carried by 3G Electric includes corrosion-resistant hazardous-location direct-drive blowers in multiple wheel diameters and motor ratings. Available models span wheel diameters from approximately 7 7/8 inches to 11 7/8 inches, with motor horsepower ratings from 1/4 hp up to 1 1/2 hp. Voltage options include 115/230V AC single-phase and 230/460V AC three-phase configurations, all with totally enclosed motor housings. Rotation is counterclockwise (CCW) across the line, and each unit ships with a drive pack. Airflow capacities vary by model and wheel size, with published ratings such as 300 cfm and 900 cfm depending on the specific configuration. The direct-drive design eliminates belt and pulley maintenance, reducing the number of wear components in the air stream.

These blowers are intended for moving air, fumes, dust, or vapors in environments where standard blowers would be subject to corrosion or where hazardous-location classification requires equipment designed for those conditions. The totally enclosed motor construction helps protect the motor from moisture, dust, and corrosive contaminants. The corrosion-resistant housing and wheel materials extend service life in applications where chemical exposure would degrade standard carbon steel components. Typical installation contexts include tank ventilation, scrubber exhaust, laboratory fume hood support, and general industrial ventilation in classified areas.

3G Electric supplies the PLASTEC line as part of its industrial equipment catalog, offering access to datasheets, model selection support, and logistics coordination for global delivery. The catalog includes 67 PLASTEC SKUs covering the corrosion-resistant hazardous-location direct-drive blower family. Buyers can reference specific model numbers such as S14XT2P150, P30XS6P075, P25XS4P050, P20XS6P025, P20XS4P033, P20XS2P100, P30XS4P150, and P25XS6P025 when requesting quotations or technical information. 3G Electric provides specification documentation and order fulfillment support for these products to plant engineers, maintenance managers, and procurement specialists worldwide.

Frequently asked questions

Common questions about PLASTEC from 3G Electric.

What motor ratings and voltage options are available in the PLASTEC corrosion-resistant hazardous-location direct-drive blower line?

PLASTEC corrosion-resistant hazardous-location direct-drive blowers are available with motor horsepower ratings from 1/4 hp to 1 1/2 hp. Voltage configurations include 115/230V AC single-phase and 230/460V AC three-phase. All models in this family use totally enclosed motor housings and CCW rotation. Specific examples include the P20XS6P025 at 1/4 hp, 115/230V AC, 3-phase; the P25XS4P050 at 1/2 hp, 115/230V AC, single-phase; and the S14XT2P150 at 1 1/2 hp, 230/460V AC, 3-phase. Each unit includes a drive pack.

What wheel diameters are offered across the PLASTEC direct-drive blower models?

The PLASTEC corrosion-resistant hazardous-location direct-drive blower family includes wheel diameters of 7 7/8 inches, 9 7/8 inches, 10 inches, and 11 7/8 inches. Models such as the P20XS6P025 and P20XS4P033 use a 7 7/8-inch wheel. The S14XT2P150 uses a 9 7/8-inch wheel. The P25XS4P050 and P25XS6P025 use a 10-inch wheel. The P30XS6P075 and P30XS4P150 use an 11 7/8-inch wheel. Airflow ratings vary by model, with published figures including 300 cfm for the P20XS6P025 and 900 cfm for the P25XS6P025.

What does 'hazardous-location' mean in the context of PLASTEC blowers?

In the PLASTEC product line, hazardous-location refers to blowers designed for installation in areas where combustible dusts, vapors, or gases may be present, or where corrosive atmospheres could degrade standard equipment. These blowers combine totally enclosed motors with corrosion-resistant housings and wheels. The direct-drive configuration eliminates belts and pulleys, reducing potential ignition sources and maintenance points. PLASTEC hazardous-location blowers are typically specified for ventilation, fume extraction, and process air movement in chemical, pharmaceutical, wastewater, and metal finishing facilities where classified area requirements apply.

Which PLASTEC blower models deliver the highest airflow?

Among the PLASTEC corrosion-resistant hazardous-location direct-drive blowers listed in the 3G Electric catalog, the P25XS6P025 is rated at 900 cfm with a 10-inch wheel and 1/4 hp motor. The P20XS6P025 is rated at 300 cfm with a 7 7/8-inch wheel and 1/4 hp motor. Airflow capacity depends on wheel diameter, motor speed, and static pressure conditions. For applications requiring higher flow, larger wheel diameters and higher horsepower configurations are available. Consult individual model datasheets for complete performance curves and selection guidance.

Are PLASTEC direct-drive blowers supplied with drive packs?

Yes. The PLASTEC corrosion-resistant hazardous-location direct-drive blowers carried by 3G Electric include a drive pack with each unit. This applies across the model range, including the P20XS2P100, P20XS4P033, P20XS6P025, P25XS4P050, P25XS6P025, P30XS4P150, P30XS6P075, and S14XT2P150. The drive pack provides the necessary components for direct-drive operation, where the motor shaft connects directly to the blower wheel without belts or pulleys. This configuration reduces maintenance requirements compared to belt-driven alternatives.

What rotation direction do PLASTEC direct-drive blowers use?

PLASTEC corrosion-resistant hazardous-location direct-drive blowers in the 3G Electric catalog are specified with counterclockwise (CCW) rotation. This rotation designation is consistent across the models listed, including the P20XS2P100, P20XS4P033, P20XS6P025, P25XS4P050, P25XS6P025, P30XS4P150, P30XS6P075, and S14XT2P150. Rotation direction is a critical specification for matching the blower to ductwork and ensuring correct airflow direction. Verify rotation requirements against system design before ordering, as incorrect rotation can reduce performance and increase motor load.
