The price per square foot (in 3rd quarter 1986 dollars) of bags by type of fabric and
type of cleaning system used is given in Table 1. The prices represent about a 10
percent range. In calculating the cost, use the gross area as determined from Table 2.
Gore-Tex fabric costs are a combination of the base fabric cost and a premium for the
PTFE laminate and its application. As fiber market conditions change, the costs of
fabrics relative to each other also change. The bag prices are based on typical fabric
weights, in ounces/square yard, for the fabric being priced. Sewn-in snap rings are
included in the price, but other mounting hardware, such as clamps or cages, is an
added cost. See the notes on Table 1 for these costs. EPA's OAQPS Cost Control
Manual can be used to obtain additional information on the cost (EPA 1990).
