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.
†
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.
‡
TB250R-4 hopper position two is supplied with a 12-8 adapter with an
eight inch cover plate as standard. Position three and four are supplied
with hand-fill lids.
