Product Description
The fan coil unit with HEPA filter consists of an outer housing with make-up air connection and exhaust
air connection, together with the internal components: HEPA filter cell with fan motor unit in a common internal
housing and a cooling coil. As an option, a prefilter can be installed.
PIFF is an FFU with a dry coil, which lowers the temperature of the air transported into the clean room through
the dry coil. In the photovoltaic new energy industry, there will be process equipment such as ovens in the clean room,
which will generate a lot of heat. The heat mainly depends on the process. Cooling water and process heat are removed
by exhaust air; at the same time, process equipment also produces acid, alkali, and organic waste gases, which need
to be discharged. All kinds of high-volume exhaust air in the clean room mean that a large amount of fresh air, which has been
treated with heat and humidity, needs to be supplemented to maintain the positive pressure in the room. When the cleanliness
level of the clean room in the photovoltaic new energy industry is required to be above ISO5,
a fresh air unit (MAU) + a clean air conditioning system with a fan filter unit (PIFF) with a dry coil can be used.
| BOX Size | 1175*1175*770mm |

| Maximum input power | <280W(Standard operating conditions) |
- The supply of fresh air and the collection of exhaust or return air are implemented by a specially designed air grill
- which is located on top of the ceiling installation frame of the PIFF.
- The power and network connectors as well as the cooling water connections (supply/return) are located at the
- side of the unit. The control valve for the cooling coil is to be provided for a single or a group of fan coil units with HEPA filters (by others).
- The fan draws air from the room via the return air intake in the outlet grill and channels the air through an optional
- prefilter to the cooling coil. The chilled air flows through the HEPA filter and is blown with high turbulence into the cleanroom via the outlet air grill.
- This design prevents a shortcut between supply air and return air. The distribution elements of the outlet air grill are
- arranged in a special design to ensure a homogeneous air distribution to all sides.
