Variable Frequency Drives

Discover the Variable Frequency Drives (VFDs) supplied and Pre-Programmed for PLASTEC blowers. Our Engineers will program your VFD to your specific PLASTEC blower for ease of installation and use.

VFDs are great devices to control the motor speed and therefore adjust flow rate and pressure in your HVAC system. They increase energy efficiency and decrease the long-term cost of an HVAC system while protecting the motor in various ways: 

• Soft start for gentler motor acceleration.
• Overcurrent monitoring to prevent excessive current flow.
• Voltage regulation to guard against voltage irregularities.
• Thermal protection against motor overheating.
• Phase detection to prevent imbalances or loss of phases.
• Stall detection to avoid motor non-rotation.
• Surge and spike suppression for voltage stability.

Unleash precision control and energy efficiency in your projects.

Key Features of the PLASTEC's pre-programmed VFDs

• Input signal 0-10V or 4-20mA
• Connect to one of PLASTEC's Fumehood Controllers with the 0-10V signal 
• Preset or Priority frequencies/speeds
• Easily adjust with PLASTEC's Dial Potentiometer
• Connect to thermal load or PTC sensor of a motor
