UNIT PERFORMANCE CURVES
FAN SELECTION
These curves indicate static pressure available at fan inlet for
a given volume when fitted inside aUnimaster dust collector.
To select the most suitable fan for a given application:
1 Determine the air volume, in m3/h, needed to entrain the
dust.
2 Read off the unit resistance, in mm W.G., at air volume
required.
3 Assess pressure drop over filter bags prior to cleaning,
usually 50 to 100 mm W.G.
4 Estimate pressure drop through connected system − i.e. between
point of entrainment and collector inlet.5 The sum of 2, 3 and 4 =
W.G. required.6 Consult graph for fan performances available.
Sack Tipping Units have K3 (1.5 kW) fans with modified outlet to
ensure adequate face velocities at the tipping hatchunder normal
operating conditions. Typically, the exhaust rate for the UMA
250STU is 1275 m3/h (750 cfm).

NOISE LEVELS
Machinery noise levels are an important consideration in the
design and selection of new equipment.Several EC Directives and
National Laws/Regulations adopting these directives make reference
to airborne noise emissions.
Actions that employers are required to comply with if employees
are subjected to a daily personal noiseexposure Lep,d of 85 dB(A)
or more are also specified.
All Unimaster dust collectors, when fitted with an acoustic
diffuser, secondary filter or absolute filter,operating an 8 hour
shift, are below this action limit.

WEIGHTED SOUND PRESSURE LEVELS
All readings were taken in normal industrial areas, i.e.

1.0 metre radius from the equipment housing
and 1.6 metres above base level, using a precision sound level
meter and octave filter.
