Methods, apparatus, systems, and computer-readable media are provided for employing an environment of sensor arrays at an air handling unit. Each sensor array can include one or more sensors for collecting data related to a portion of an air handling unit. Additionally, each sensor can be in communication with each other and/or each sensor array can be in communication with a remote server for processing the collected data. The collected data can be correlated in order to identify how various portions of the air handling unit are affected by other portions of the air handling unit and other systems that are external to the air handling unit. For instance, certain properties of motor and/or filter operations can be indicative of heating and/or cooling coil fouling and/or changes in air pressure of rooms served by an air handling unit.

Sensor array environment for an air handling unit

The present disclosure is related to an air filter operation and use modification system. The system properly determines average filter resistance based upon determined air velocities in the air handling unit. Once accurate average filter resistance is determined, various energy use measurement determinations can be made for a proposed filter in the system. Such determinations can be based on estimated or desired filter energy use measurements. The system can modify the air handling unit operations to meet the proposed filter energy use measurements. Furthermore, the user will have the ability to review the range of potential operational points and then be able to select the service cycle based on the air handling unit owner's preferred preventive maintenance and budget cycles.

An apparatus having one or more filters positioned by a connection member. The connection member orientates one or more filters at a transverse angle relative to the horizontal to drain contaminants from the filter.

Auto-draining filter apparatus

A HEPA filter which utilizes spun bond scrim material and ePTFE membrane for use in an aseptic pharmaceutical filtration air handling system for installation and testing is provided. The installation and testing configuration includes the ePTFE filter with a low or ultra-low concentration of challenging aerosol in the upstream side of the filter along with a scanning device for determining the upstream concentration, all completed in situ within a pharmaceutical air handling system. At the downstream side of the ePTFE filter is positioned another scanner which may be a discrete particle scanner for calculating the penetration percentage of the aerosol through the filtering media of ultra-low concentrations. The system and configuration allows for exposure to ePTFE filtration media for certification by low or ultra-low concentrations of oil based challenging compounds.
