4. Element Cleaning
Some types of Solberg inlet filter elements can be cleaned and reused.
However, damage can occur to an element during cleaning so it is imperative
that care is taken during disassembly, cleaning and re-assembly. Damaged
elements can allow particulate bypass, which will damage rotating equipment.
A. Polyester Element: The polyester element may be washed in warm
soapy water, vacuumed, gently blown out or replaced. The element
should be dry before reinstallation.
B. Paper Element: The paper element may be lightly blown with low
pressure air. It is disposable and in most cases should be replaced with a
new element.
C. Polyurethane Prefilter: The prefilter may be washed as a sponge or
replaced to give the element a longer service life.
D. Stainless Steel Wire Mesh Element: Cleaning instructions similar to
polyester, except mild solvents may be used.
E. Activated Carbon Element: Not cleanable
F. Polypropylene Element: Cleaning instructions similar to polyester
G. Nomex Cloth Element: Cleaning instructions similar to polyester
If you are not confident that the integrity of the element was maintained during
cleaning, it is recommended that a new element be installed. Also, spare parts
such as gaskets, wingnuts and washers can be supplied upon request.

PROCEDURES
1. Installation.
A. Maximum inlet gas stream temperature for most Solberg inlet vacuum
filter products is 105 degrees C. Temperatures in excess of this could
cause damage to elements, media and elastomers.
B. Direction of flow is typically from the outside of the element to the inside of
the element. Most products have arrows indicating direction of flow on
inlet and outlet ports.
C. Ensure that pipe/flange connections are adequately sealed so the
potential for leaks is reduced to a minimum.
