Meidinger 1605 Blower

Meidinger Blower (Continued) Instructions and Engineering Data for Meidinger Blowers
NOTE: For larger air requirements, please inquire into the Meidinger slow speed blower line. These
have the same qualifications as the high speed blowers except they are usually installed in a remote area
as a central blower for the organ. These have sheet metal housings with 1680 R.P.M. ball bearing motors
and a built-in intake sound silencer. When ordering, be certain to specify outlet direction. Larger sizes are
available up to 100 h.p.
Oiling The oil cups are fitted with wool yarn wicks. Before starting, fill both cups with a lightweight electric
motor oil. The wick will absorb the oil, so repeat this several times.
Frequency of oiling depends on how much the organ is used. To be on the safe side, re-oil every service
call.

Horsepower
No attention need be given towards lubricating the ball bearing blowers Direction of Rotation
The blower will produce air in either direction, but rotation in the wrong direction will result in overloading, reduced capacity and eventually will cause the
windings to burn out. Immediately after wiring, make sure that the rotor is rotating in the direction of the
arrow.
Motor and Temperature Be certain that the fuse rating is no greater than
shown on the blower. Also, a slo-blo fuse is recommended. Although the motor winding temperature
will stand 120ºC (248ºF), the motor housing temperature should not exceed 65ºC (149ºF). It is normal
for the motor to reach its full speed within 15 seconds.
If full speed has not been reached within 30 seconds, turn the power off. Connect a voltmeter to the motor
box and reapply power. Upon starting, the voltage should not drop more than 10% of the line voltage.
Dynamic/Static Ratio
.7 .75 1.1 1.2 1.6 2.1 2.6 3.1 3.3 3.6
The static pressure will be approximately 1 to 2 above the dynamic pressure. There will naturally be
a larger difference between the static pressure and the regulated pressure.
High Elevation Operation At higher elevations, the C.F.M. will remain the
same. The motor will operate cooler, but the pressure will drop 4% per 1,000 feet. (i.e.: The pressure
drop in Denver at 5,000 feet will be 20%.)
Delivery on all the above blowers is 14-18 weeks.
