PLASTEC

PLASTEC blowers are constructed using corrosion-resistant materials such as fiberglass-reinforced plastic (FRP) or polypropylene for the housing and wheel. These materials are selected for their ability to withstand exposure to acids, alkalis, and other corrosive chemicals commonly found in industrial exhaust streams. The totally enclosed motor housing is also sealed to prevent corrosive gases from contacting internal motor components. Specific material grades vary by model, but the design prioritizes chemical compatibility for continuous operation in harsh environments.

Yes, PLASTEC offers hazardous-location models, such as the P20XS6P025, which are designed for use in environments where flammable gases, vapors, or dust may be present. These units meet the requirements for Class I, Division 2 or similar classifications, depending on the specific model. The motors are totally enclosed and may include additional sealing or spark-resistant construction to reduce ignition risks. Always verify the specific model's certification and suitability for your classified area before installation.

The lifespan of a PLASTEC blower depends on operating conditions, including temperature, chemical concentration, and duty cycle. In typical continuous-duty applications with proper maintenance, these blowers can operate for 10 to 15 years or more. The direct-drive design reduces wear by eliminating belts and pulleys, while the corrosion-resistant housing extends service life in aggressive environments. Regular inspection of the motor bearings and wheel balance is recommended to maximize longevity.

Selection is based on required airflow (cfm), static pressure, and system resistance. PLASTEC blowers are available with wheel diameters from 6 to 11 7/8 inches, delivering 275 to 900 cfm at various pressures. Motor horsepower ranges from 1/4 to 1 1/2 hp, with single-phase or three-phase options. Use the manufacturer's performance curves to match the blower to your system's operating point. 3G Electric can assist with cross-referencing specifications to ensure proper sizing.

PLASTEC blowers are designed for indoor use in corrosive environments, but they can be installed outdoors if protected from direct weather exposure. The totally enclosed motor provides some protection against rain and dust, but prolonged exposure to UV radiation or heavy precipitation may degrade the housing material. For outdoor installations, consider adding a weather hood or shelter to shield the blower from the elements. 3G Electric offers weather hoods as accessories for certain models.

Maintenance is minimal due to the direct-drive design. Key tasks include periodic inspection of the motor bearings for noise or vibration, cleaning the wheel and housing to prevent buildup of corrosive residues, and checking electrical connections for tightness. The motor bearings are typically sealed and require no lubrication. For hazardous-location models, verify that all seals and enclosures remain intact. A maintenance schedule of every 6 to 12 months is generally sufficient for most applications.
