SAFETY INFORMATION

NAVCO Bin Hopper (BH) series vibrators are intended to promote flow of dry bulk solid materials. BH vibrator models are available in air
cushioned (SG0), repetitive impacting (IG0) and single impact (IGT).
Repetitive Impact BH Vibrator
IGO: vibrator operates by alternately directing air pressure
from one end of the housing to the other through a ported
piston. An air cushion is formed in the top of the housing but
not at the bottom of the housing. This allows the piston to
impact the housing base. Variable frequency and amplitude
is obtained by regulating the air pressure from 20 to 60 psi.
Single Impact BH Vibrator
IGT: vibrator operates by using air pressure to create a single
impact of the piston into the housing base.

Vibration Technology for Processing Bulk Materials
Silent BH Vibrator
SG0: vibrator operates by alternately directing air pressure
from one end of the housing to the other through a ported
piston. An air cushion is trapped at each end of the piston
stroke, preventing the piston from impacting the housing.
The repetitive linear motion of the piston creates vibration
energy. Variable frequency and amplitude is obtained by
regulating the air pressure from 20 to 60 psi.
NOTE:
Operating BH vibrators over 60 psi is not recommended.
Force output peaks at 60 psi. Overpressure reduces vibrator life.
Vibrators must have adequate lubrication at all times. See the
lubrication section for recommendations.
