UNI-BASEUltra-Wide BasePlates/ComponentsRotary Positive BlowersThese wide base plate products accommodatea variety of blower package designs. The UNI-BASE package and the USI-BASE base plateuse the same basic base plate and dischargesilencer. The UNI-BASE package includes theUniversal Silencer model URBN high-side inletsilencer and CCF inlet air filter, while the UNI-BASE base plate is only the basic plate and theURBY discharge silencer. Please see page 2 forperformance and sizing information for the URBYseries silencers, page 2 for information on theURBN series silencers, and page 9 in Filters andFilter-Silencers (#94-1553) for performance data,weights and dimensions of CCF filters.UNI-BASE PackageCCF (see Filter and Filter-SilencersTechnical Literature #94-1553 page 9)URBN (see page 15)URBY (see page 7)UNI-BASE Base Plate OnlyURBY (see page 7)UNI-BASE Base Plates/Components Part NumbersSize22.53456UNI-BASE Package80-187380-187480-187580-187680-187780-1878Base Plate Only URBN Only URBY Only CCF Only55-202-ABP55-225-ABP55-203-ABP55-204-ABP55-205-ABP55-206-ABP55-502-AA55-525-AA55-503-AA55-504-AA55-505-AA55-506-AA55-202-AA55-225-AA55-203-AA55-204-AA55-205-AA55-206-AA34-L02-TT*34-L25-TT*34-L03-TT*34-L04-TT*34-L05-TT*34-L06-TT**Specify “P” at end of part number for unit with pleated paper elements, “F” for pleated felt or “W” for wire mesh.Refer to Filter and Filter-Silencers Technical Literature booklet #94-1553 for filter element details.© 2011 Universal Acoustic & Emission Technologies, Inc.
