Abstract: An air curtain air cleaner and sanitation system that incorporates established active bipolar ionization technology with threshold air delivery air curtains that provide conditioned airflow to form a lamination airflow barrier typically between openings in a structure.

Abstract: Tools, strategies, and techniques are provided for enhancing the control and operation of air curtain devices. The air curtain device can be provided with a computer system programmed to receive input data from various sensors and to communicate the sensor data to a wireless mesh computer architecture. An algorithm module can be programmed to determine adjusted settings or parameters for the air curtain device in response to the sensor data and/or other data sources such as external data sources. Data may be obtained from multiple air curtain devices configured for cooperative performance, and operating parameters or settings may be adjusted in connection with one or more of the multiple air curtain devices. A control device of the air curtain may be provided with a unitary structure suitable for efficient installation of multiple control harness connectors thereon to supply power and/or to establish data connectivity with multiple components of the control device.

Abstract: An air curtain resistant heating system including multiple independent heating coils integrated on blower housing. The multiple heating coils defining a pre-inflow venturi air pattern for increased heat transfer before fan cage internal flow vortex dependent on housing cage opposed openings. Coil orientation placement assures limited impact to effect blower pressure and therefore minimizes loss of air performance parameters while heating air flow in a pre-inflow venturi air pattern. Multiple phase electrical supply for multiple paired heating coils positioned in corresponding multiple blower fan units in an air curtain assembly.

Abstract: The present invention provides a blade seal for use with a blade that compresses the blade seal to form a seal across a sealing junction. The blade seal includes a recessed ridge for receiving the blade and having a plurality of ridge contact points. When the blade compresses the blade seal to form the seal, the plurality of ridge contact points contacts the blade. The blade seal also may include side lobes extending from the recessed ridge and having respective lobe contact points. When the blade compresses the blade seal, the lobe contact points also contact the blade. The blade seal also includes a secondary sealing portion. When the blade compresses the blade seal to form the seal, the recessed ridge presses against the secondary sealing portion. The multiple contact points between the blade seal and blade, and the presence of a secondary sealing portion, enhance the efficacy of the seal.
