No. 222 LETZ WITH EXHAUST FAN 
AND SACKING TOWER EQUIPMENT 
Letz heavy-duty grind- 
ers are considered incom- 
plete without the ball- 
bearing exhaust fan. The 
fan aerates, cools and de- 
livers the ground feed. It 
mixes feeds, saves hand- 
ling and rehandling work, 
stores the ground feed 
away more safely. 
With exhaust fan you 
can dispose of the ground 
feed as you wish. You 
ean add a sacking tower, 
: = swinging wagon box tow- 
Pre er, or build up a feed 
distribution installation of your own, at low cost, by adding 
pipe, elbows, valves and branch lines to make the work of the 
fan still more valuable. 
Blow your ground feed into overhead storage bins, into 
self-feeders, or to 3, 4, 5 or more storage locations within 100 
feet radius from the grinder. 
This is the way to meet the feed handling job, to cut costs 
and to add convenience! Why not make this installation 
now!
