  • 120-, 208–230-, and 277-volt, single-phase EC motors
  • Solo/sync motor control technology

  • CFM: 100 to 4,100 CFM
  • Optional integrated VAV box with direct digital controls (DDC) that allows for a bundled offering with lower total installed costs.
  • Available with PSC or EC motor options to meet a variety of fan powered application requirements.

  • FlowStar air measuring probe reduces energy costs and noise while maintaining comfort in the zone.
  • Standard and low-height units with PSC or EC motor options to meet a variety of fan-powered application requirements.
  • OSHP-OSP-certified in compliance with CBC and IBC to ensure cabinet integrity throughout the installation process and seismic events.

  • Consider upgrading older style controls with the ENVIRO-TEC ZEC500 or ZEC510 DDC (direct digital control) retrofit kit. These DDC controllers offer unparalleled accuracy, dependability, and sequence options. Like the RFT-MS measuring station, ZEC500 and ZEC510 retrofit kits are a breeze to install in retrofit applications.
  • If you need to convert mechanical, constant-volume terminals to a variable air volume configuration, energy-saving retrofit terminals are a great option. ENVIRO-TEC offers two single-duct models: the SGX exhaust valve and the SSX stainless-steel terminal.
  • Provided with air balancing taps and an airflow calibration chart.
