1.6 Assembly – General Comments
As indicated previously, the individual components that will comprise
the filtration system may ship separately and will be required to be
installed on site. The SAAF PORTA-Scrubber is a self-contained
product and, consequently, a minimum amount of assembly is
required. Refer to section 3.0, Installation Instructions, of this manual
for further detailed instructions. Consult with an experienced installer
to obtain an accurate estimate of the time, personnel, and equipment
resources and tools that will be required to complete the assembly
and installation of the filter system. Site assembly will be limited to
moving and lifting individual components, screwing components
together, and caulking. The PORTA-Scrubber weights and dimensions
can be found on the product drawings. Packages of the chemical
media will typically have a maximum weight of approximately 50
pounds (23kg). Particulate filters will typically weigh less than the
chemical media filters.
1.3.3 Particulate Filters:
The standard particulate prefilter will be
AAF PolyKlean Blue pads. Depending on the size of the PORTA-
Scrubber ordered, a round 24" diameter x 2" deep or a round 37"
diameter x 2" deep may be supplied. PolyKlean Blue 2" deep
filters are individually packaged.
Note that other optional or special filter arrangements may be
supplied depending on the requirements of the project. Check
the purchase order and the AAF submittal drawing(s) for details.
