COVID-19 air filtration

In light of the WHO's confirmation that there is "emerging evidence" of airborne transmission of Corona virus virus Lev-co has put together a series of products that may assist you in designing and procuring solutions that limit the spread of airborne particles such as the corona virus. In this section you will find equipment that addresses each these components required in a ventilation systems tailored to capture and filter and return air the your facilty:

  • Capture hoods and devices
  • Transport ducts and hoses
  • Powered and non-powered filter housings and air cleaners
  • Electrical controls (VFD and differential Pressure controls
  • Booster fans
  • Supply Air Nozzles to direct the flow to the capture hoods and devices.

    Here are a few links to articles written about the capture and control of Covid-19 emmisions:

    STANDARD FEATURES:
  • Built-in shutters that automatically open when the fan starts and gravity closes when the fan stops
  • heavy duty aluminum housing
  • Plated steel OSHA motor mount/guard
  • Single or variable speed operation
  • Aluminum fan blades on steel hub
  • Totally enclosed motors
  • (12-13) VFD System with Manual Dampers and Pressure Transmitter - Type 2
    Image for Model 954
    Lev-co’s LEVEL 2 VFD system allows for “On-Demand” flow control of an exhaust fan for industrial ventilation applications.
    FUNCTION:
  • The fan is first activated by an "Optional" switch attached to the damper, hose reel, hose drop, current sensor*, etc. When this switch closes the fan turns on.
  • Once the damper in the 1st drop opens, a digital pressure transmitter senses the pressure in the main duct downstream of the fan and allows the VFD to actively control motor speed as a function of duct (negative) pressure.
  • As more dampers are opened and closed the fan speed increases and decreases in order to provide the required flowrate at each drop. This permits constant, effective exhaust at a target duct pressure no matter how many dampers are open or closed. Flow "On Demand"
  • The fan turns off when the last operator has no more demand
    The following components are included in this “Level 2” VFD solution:
  • VFD (Variable Frequency Drive)IP65
  • Control Panel IP65 c/w with the following components:
  • HOA Hand/Off/Auto selector switch
  • ”Fan on” Pilot Light
  • Pressure Transmitter 4-20 ma
  • Digital Pressure Gauge 1-10” WG
  • 100’ of pneumatic tubing
  • 1/8” MPT hose barb (for connection to duct)
  • (12-14) VFD System with Manual Dampers and Speed Potentiometer - Type 1
    Image for Model 953
    Lev-co’s LEVEL 1 VFD system allows for simple VFD speed control, acceleration and deceleration and sound level management for all of Lev-co's exhaust and filtration solutions.
    FUNCTION:
  • The fan is activated by a small local control panel.
  • Acceleration and deceleration settings can be programmed into the VFD in order to eliminated "Peak" demand charges and feedback from the motor.
  • As required, the flow rate can be increased and decreased according to the demand required by the application.
  • Additionally, great reductions in sound level can be achieved by adjust the flow
    The following components are included in this “Level 1” VFD solution:
  • VFD (Variable Frequency Drive)IP55
  • Simple potentiometer speed control plus on/off switch and fan running indicator
  • (12-15) VFD System with Powered Dampers and Pressure Transmitter - Type 3
    Image for Model 955
    Lev-co’s LEVEL 3 VFD system allows for “On-Demand” flow control of an exhaust fan for industrial ventilation applications.
    FUNCTION:
  • The fan is first activated by an "Optional" switch attached to the hose reel or hose drop. When this switch closes the fan turns on and opens the first motorized damper.
  • Once the damper in the 1st drop opens, a digital pressure transmitter senses the pressure in the main duct downstream of the fan and allows the VFD to actively control motor speed as a function of duct (negative) pressure.
  • As more dampers are opened and closed the fan speed increases and decreases in order to provide the required flowrate at each drop. This permits constant, effective exhaust at a target duct pressure no matter how many dampers are open or closed. Flow "On Demand"
  • As each hose reel or hose drop returns to its stored position, the damper on each drop closes.
  • The fan turns off when the last operator returns the hose to its stored/recoiled position
    The following components are included in this “Level 3” VFD solution:
  • VFD (Variable Frequency Drive) IP55
  • Control Panel IP55 c/w with the following components
  • HOA Manual/Off/Auto selector switch
  • Step-Down transformer used to supply 24 volt dampers
  • ”Fan on” Pilot Light
  • Pressure Transmitter 4-20 ma
  • Pressure Gauge 1-10” WG
  • 100’ of pneumatic tubing
  • 1/8” MPT hose barb (for connection to duct)
