SPECIFICATION NOTES
*
Maximum throughput rates are based on 35 lb/ft 3 pelletized
material, using all standard valve sizes. Use of reducer inserts
will lower the rate shown.
Throughput rates are based on:
• A 4-position blender recipe of 20% regrind, 80% natural,
3% color and 2% additive material.
• A 6-position blender recipe of 20% regrind, 80%
natural, 3% color at position 3, 2% additive at position 4,
3% additive at position 5 and 2% additive at position 6.
†
The optional flow control valve will mount inside the chassis in
the space of the manual slide valve. Conair recommends
using the optional flow control valve when mounting the
blender on a stand, surge bin or hopper.
‡
TB250-4 hopper positions two and four are supplied with
12-8 adapters with eight inch cover plates as standard.
TB250-6 hopper position two is supplied with a 12-8 adapter
with an eight inch cover.
