Partial enclosures cover key pieces of equipment like a blower or vacuum pump, while leaving other large system components exposed. This style of enclosure is chosen to provide weather protection for the most valuable pieces of your system or to reduce sound coming from the noisiest equipment. For greater protection from noise and weather view our designs that fully enclose the entire package.
Our enclosures are built to your spec at any size, however this style of enclosure is most commonly used on large blowers such as the Roots RAS-J and RGS-J series.
Our most popular option for this style enclosure is galvanized steel, which is cost effective, durable, and resists rusting. This enclosure can also be built with aluminum, stainless steel, powder coated steel, or painted steel depending on your specific needs.
Our most popular insulation option is 2” Rockwool mechanically fastened to the interior skin of the enclosure; this is a budget friendly option that provides typical noise reduction of 11 to 12 dBA at 3’ from the enclosure. Other insulation materials are available including foam, recycled carpet pads, foam with reinforced mylar scrim surface and decoupled foam. A perforated liner is also available to protect personnel from coming into contact with the insulation and minimize damage; a liner is recommended when the enclosure will be opened for maintenance on a regular basis.
A partial enclosure is typically part of a larger package build and would be mounted to the fabricated steel sub-base that supports the rest of the package.
Air is typically introduced into the enclosure on the ends near the bottom and exhausted at or near the top. Ventilation air must be used to eliminate overheating of a blower package. If you elect to use the enclosure for other equipment, please specify the expected heat load and we can offer solutions to best suit your needs.
Exhaust fans are a common option. We can supply fans for the enclosures for any of the following voltages: 120 Vac/1/60, 208 Vac/1/60, 208 Vac/3/60, 240 Vac/3/60, 277 Vac/1/60, 460 Vac/3/60 (also referred as 480 Vac/3/60), 380 Vac/3/50, 220 Vac/1/50
