or "sea coast" installations. Specify the various
systems (utilizing the word "or") offered by three
competitive equipment selections. This approach is
by far less costly than specifying custom corrosion
protection.
Manufacturer's standard off-the-shelve
anti-corrosion options for "coastal" or "sea coast"
installations also vary with type and size of HVAC
equipment.
After thorough investigation of the commercial
market, determines manufacturer's standard
off-the-shelve anti-corrosion options are not
available for the selected equipment, contact the
Mechanical Design Branch, NAVFACENGCOM for
consultation if the need for this protection is
considered mandatory by the station.
For installations at MCAS Cherry Point and MCB Camp
LeJeune, including New River, and installations at
NAS Oceana including Dam Neck, specify corrosion
protection for all outside, and specific inside HVAC
equipment exposed to the weather. Follow the
guidance specified in the criteria NOTE above.

Air Filters
**************************************************************************
NOTE: Select filters based on the functional needs
of the area served, including indoor air quality.
The combination of the extended surface pleated
panel filters and the extended surface nonsupported
pocket filters or the cartridge filter of the same
efficiency are intended to fulfill the filtration
requirements in UFC 3-410-01, Design: Heating,
Ventilating, and Air-Conditioning for areas where
indoor air quality is of primary concern.
In the event the retention of efficiency values in
the specification becomes cumbersome, the
requirements may be revised by referring to the
efficiencies indicated on the drawings, to show for
each air handling unit or system the efficiency of
the air filters required, and the maximum initial
**************************************************************************
Air filters shall be listed according to requirements of UL 900, except
high efficiency particulate air filters of 99.97 percent efficiency by the
DOP Test method shall be as listed under the Label Service and shall meet
the requirements of UL 586.
