Euroemme LF Light Filter
A light filter is the ideal equipment required
to reduce the light ingress through air stream passages. A
typical example is the poultry industry In order to obtain
optimal breeder-bird performance in pullet houses, both light
intensity and the number of light hours each day must be precisely
controlled.
By controlling lighting it is possible for breeder birds
to reach sexual maturity at the optimal time and therefore
to stimulate the beginning of egg-production.
LF light filter is constructed of high
grade polypropylene resistant to wear and tear, ultra violet
rays from the sun, as well as the strong high-pressure washers
used in farm cleaning techniques. The square frame housing
the light filter vanes or media, is made of a strong epoxy
pre-coated and galvanised sheet-steel.
Special designed clips provided with each kit, allow the
mounting of a light filter directly onto a Euroemme™
fan, on the suction side of the fan, as a perfect match
in air-flow, efficiency and light lux reduction. To improve
aerodynamic efficiency and reduce pressure losses the light
filter design has been developed in Munters euroemme's
R&D lab. The test chamber has been built according to ANSI / AMCA 210-85 Figure 15 specifications.
Construction details and airtightness have been verified by
personnel of the BESS Lab at the Agricultural Engineering
Dept, University of Illinois USA.
Plastic Waves and Housing
The
vertical plastic vanes are designed for laminar air-flow in
order to avoid any turbulence resulting in higher than necessary
pressure-drop while air passes through them. When installed
correctly in the vertical configuration, the vanes assure
long lasting operation without dust build up allowing the
pressure-drop to remain constant.
Light filters are delivered in knock down kit form in order
to reduce transportation cost and possible damages during
transport, and do not require the necessary use of glues or
chemicals in assembling the filters. The vanes are equipped
with self locking clips that are utilized by simply pushing
two vanes together. A complete light filter can be mounted
in less than 20 minutes.
Equipment
- Housing frame made of strong pre-coated and galvanised
sheet-steel
- Vanes made of high resistance polypropylene with UV protection
- Simple and easy installation
- Special clips supplied for easy coupling with Euroemme
fan housing. Only one person is needed to mount or to remove
the light filter
- Special design of vertical plastic vane media with reduced
pressure drop
- Air passing through the vertical vanes ensures a self
cleaning feature
- A unique light reduction performance coupled with low
pressure drop. Light reduction, from exterior lux values
of 7,000 lux, to interior values of 0.04 lux, with a corresponding
pressure drop of 2.5 Pa at an airvelocity of 1.5 m/s
- Every light filter package is individually checked for
quality


To keep the total static pressure within desired limits,
the area for inlet light filters must be increased over the
area of light filters used on the exhaust fans by approximately
150%.
