Construction:
Housing
The PCU housing is to be constructed of 430 SS of polish 2B or better. All metal in contact with the air-stream is to be constructed of 430SS. 1500°F Ceramic based gasket must be in place for all internal seams exposed to airflow. High temperature weatherproofing gasket must be used on all exterior seams.
 
Base
The base shall be constructed of galvanized steel for improved rigidity. Base shall be structurally reinforced to accommodate the filter assembly.
 
Pre-Filter Section
The pre filter section shall include 2 inch deep steel washable permanent filters. Filter frames shall be constructed of steel. Disposable Grease Lock filters (optional) placed upstream of the permanent filters shall be provided for improved filtration and longevity of High Efficiency Filters. Filters shall be arranged in a v-bank configuration to increase filter area and reduce static pressure. All filters shall be removable without the use of tools through side access doors with lift and turn latches. Filters are to be cleanable with a water hose and soapy water.
 
High Efficiency Filter Section
The phase two filters shall consist of 4 inch deep rigid cell extended surface filters. Filter cell sides shall be constructed of metallic frame with downstream mesh for durability. Beverage board filter sides shall not be permitted. Filters shall be arranged in a v-bank configuration to increase filter area and reduce static pressure. All filters shall be removable without the use of tools through side access doors with lift and turn latches. Filters are to be rated MERV15 minimum in accordance with ASHRAE standard 52.2 and have a minimum average arrestance of 98% in accordance with ASHRAE 52.1-1992. High Efficiency module must be installed downstream of pre-filter module.
 
HEPA Filter Section
The phase two filters shall consist of 4 inch deep rigid cell extended surface filters. Filter cell sides shall be constructed of metallic frame with downstream mesh for durability. Beverage board filter sides shall not be permitted. Filters shall be arranged in a v-bank configuration to increase filter area and reduce static pressure. All filters shall be removable without the use of tools through side access doors with lift and turn latches. Filters are to be rated MERV17 minimum in accordance with ASHRAE standard 52.2. HEPA module must be installed downstream of High Efficiency filter module.
 
Odor Control Media Section (Optional)
The phase two filters shall consist of 4 inch deep rigid cell extended surface filters. Filter cell sides shall be constructed of metallic frame. Beverage board filter sides shall not be permitted. Filters shall be arranged in a v-bank configuration to increase filter area and reduce static pressure. All filters shall be removable without the use of tools through side access doors with lift and turn latches. High Efficiency module must be installed downstream of pre-filter module.
 
Advanced Filter Monitoring System (Optional)
The Advanced Filter Monitoring includes a module that provides the necessary precision pressure measurements for accurate monitoring of the complete system. Based on the measurements the AFM will initiate suitable actions via the electric control package in case of a fault. Direct access to the operating conditions are also provided through the use of a HMI (Human Machine Interface), which is conveniently located on the PCU.
