IV EC, Jet Fans

IV EC Jet Fans

High Induction Compact Centrifugal Jet Fan

The lowest profile induction jet fan on the market. The IV Smart EC combines the performance factors including airflow, induction, thrust and throw to more effectively reduce CO levels and achieve a Dilution Ventilation Strategy in the most energy efficient manner.

AMCA Certified

Certified and tested in accordance with the ANSI/AMCA 250 Laboratory Methods of Testing Jet Tunnel Fans for Performance and the ANSI/AMCA 300 Reverberant Room Methods for Sound Testing of Fans.

Standard Control Options or Modbus/BACnet Ready

Standard speed control options include PWM, 0-10V, and speed feedback reference. Optional Modbus communication capability provides seamless integration with the Building Automation System. Modbus communication allows for complete control and monitoring of the fan. BACnet communication is available when paired with the Protonode Gateway Accessory (Item# 498173).

High Performance in a Small Package

Produces 11N Thrust, Induction Factor of 28 and Throw distance of 129’ (39.5m) at Terminal Velocity 196 fpm (1m/s).

EC Driven

EC motor enables Demand Control Ventilation and reduces energy consumption on average 30%. Allows for soft start and eliminates need for a motor starter & VFD.

Low Profile Design

Height of less than 5.9” and a footprint of 31.5” x 22.4” makes it the industry’s most compact Centrifugal High Induction Jet Fan.

Easy Installation

Includes large, easy access electrical box with quick-connect lever terminals and weighing only 45 lbs., makes installation quick, easy and safe.


The casing is made of of galvanized steel, for best corrosion protection.

Compact casing for thin ceiling height with variable outlet, depends to the model.


The IV fans use aerodynamic radial impeller for maximum thrust and low noise emissions. These are made out of galvanized steel or aluminum, dynamically balanced and paired with corresponding IEC motors with efficiency IE3 or EC motors.


Depending on the type, IV fans are designed with high temperature motors for temperature classification (insulation class B or H) up to F400 (400°C/120 min), AC or EC Motors. The Motors are suitable for 50 Hz and 60 Hz.

Motor protection

Depending on the type, AC motors have an integrated thermal protection with manual (electrical) reset, prewired integral thermocontact TK or thermistor PTC with leads to a motor protection device.

Fans with EC motors have an integrated electronic thermal protection including locked-rotor protection and soft-start.


EC motors with built-in potentiometer to adjust working point can be also controlled by external signal 0-10V.

EC motors, depending on the type are also equipped with ModBus communication or alarm signal.   

AC motors can be controlled by 5-step, stepless speed regulator, D/Y switch or frequency converter.


The IV fans are for horizontal installation.
