Indoor air quality (IAQ) is just as important in unoccupied buildings as it is in those with personnel. The equipment inside control rooms is costly and often sensitive to dust and other particulates in the environment.
ASHRAE standards for many industrial areas recommend outside air to be filtered at a minimum with 30% dust spot efficiency (MERV 8) pre-filters and 85%–90% (MERV 11-14) final filters.
To help meet those recommendations and combat ingress of contaminants, we offer several types of filters. In fact, we also offer condenser air inlet filters that help protect the condenser section in areas where large debris is prevalent.
Particulate filtration efficiency is denoted by a minimum efficiency reporting value (MERV) standardized in ASHRAE 52.5.
These filters are typically used as final outside air filters placed in the airstream after our standard filters.
Available for InPac® and InPac® pressurization systems, Specific Systems® chemical filter option can be used for commercial applications, industrial applications, manufacturing facilities, or any other applications where the control of gaseous contaminants may be a concern. The Specific Systems® ChemPac is an excellent choice for ventilation air correction in areas of non-attainment per ASHRAE Standard 62.
Each Specific Systems® ChemPac chemical filter housing includes:

Cotton seed filters are designed to prevent coils and fins from clogging due to cotton seeds, dandelion seeds, and other types of floating debris, reducing maintenance costs from coil cleaning, and helping prevent compressor failure due to frozen coils. The filters will also help increase the efficiency of the compressors, keeping them running at engineered capacity.
Filters are best used in remote environments where natural debris is prevalent, and are not intended to be used for dust.
Cotton seed filters are made from industrial grade vinyl mesh with a non-stick surface for ease of cleaning. Filters resist mold and mildew, and are UV resistant for long-life (up to 15 years in many cases).
Filters feature either standard bolts or strong, quick release toggle fasteners with reinforced binding for easy maintenance while resisting heavy winds without tearing. The filters can be cleaned with a broom or brush instead of a powerwasher, reducing tools needed for maintenance on remote sites, and potentially eliminating the need for removal of the screens.
