3.3 Limits of use
The
WAMFLO
®
filters operate under the following conditions:
1)
Maximum permitted temperatures of the air flow:
POSITIVE:
80° C continuous
100 °C peak, , maximum 60s
NEGATIVE:
-20 °C
NOTE:
For pneumatic timer, the minimum temperature is - 5 °C (-15 ° C with two drying phases).
2)
Maximum acceptable static pressure of filter body:
POSITIVE:
750 mm H
2
O
(0,075 bar - 7,5 kPa)
NEGATIVE:
-500 mmH
2
O
(-0,05 bar - 5 kPa)
Maximum surface temperature (ATEX Directive)
The maximum temperature developed by the surfaces of the filter is shown on plate and is related to the stand
-
ard ambient conditions: T amb: -20 / +40 °C.
Operation zone (ATEX Directive):
The round dust collector is designed and tested to work in areas with potentially explosive atmosphere classi-
fied as zone 22 or 21.
Directive ATEX Directive defines:
1)
zone 22:
A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur
in normal operation but, if it does occur, will persist for a short period only.
2)
zone 21:
A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur
in normal operation but, if it does occur, will persist for a short period only.
