air handling units YAH

Air Handing Units YAH Series YORK YAH series ceiling-mounted air handling units are terminal points of central air-conditioning systems. They are designed for fresh air units or to cool,, humidify and de-humidify, filter and clean the air, etc. The conditioned air can be delivered to locations across various distances via specially designed ducts. The units are especially suitable for the air-conditioning of commercial buildings and industry applications. YORK YAH series air handling units have 0 different models. The cooling capacity ranges from 8kW to 5kW, and air flow from 500m 3 /h to 5000m 3 /h. Rated external total ranges from 80 to 30 Pa. More external total can be provided for flexible application. Each unit is made from galvanized steel with 5mm thick fiberglass inner insulation. It contains a built-in cooling coil and fan, and externally mounted nylon air filters. Cooling and ing coil use copper tubes with corrugated fins. The fan, motor and belt pulley are all high-quality products producing stable and efficient performance. The fan is a forward curved centrifugal model that works on double air inlets. The motor features IP55 and a type F insulation with self-lubricating bearings. The externally mounted filter can be withdrawn from side or bottom.
