A.BLOWER PACKS

(1)Optional blower packs are used to distribute steam to localized areas such as computer rooms or in areas that do not have a built-in air distribution system.

(2)Blower packs are available integrally mounted on humidifier BOBP, (See Figure 27.) or detached and field-piped and wired to humidifier RMBP. (See Figure 28.)

(3)Blower packs consist of a matching powder coated steel cabinet containing: three axial blowers with finger guards powered by 120 VAC or line voltage humidifiers, with built-in multi-tap transformer (when necessary), fuse, high temperature plastic distributor with stainless steel lid, horizontal and vertical adjustment knobs for directional control, built- in thermostat to activate blowers, speed control rocker switch and safety loop relay.

(4)Refer to Table 22 for ceiling and frontal clearances required for blower packs. Dimensions apply to both built-on and remote-mounted versions of blower packs.

(5)Mount remote blower pack(s) using factory supplied wall mounting bracket with clearances as recommended in Table 22.
