All three series offer 2, 4, 6 and 8-pole models and most are available in both 50Hz and 60Hz versions.
A small DC-powered vibrator is also available.
Invicta pneumatic vibrators are available in three versions:.
Type BCAR - double air-cushioned for reduced noise, continuous operation.
Type BCIR, designed for continuous impacting - air-cushioned on the return stroke.
Type BSIR, a single-impacting model normally controlled by a solenoid valve and timer and capable of delivering up to 100 impacts per minute.
All models comply with EN13461-1 and ATEX Directive 94/9/EC for use in Group II Category areas, Gas (Zones 1 and 2) - Temperature Class T5, and Dust (Zones 21 and 22) - Temperature Rating 100C.
Two types of hydraulically powered vibrator are available.
The Type HV is a single shaft machine similar to BLz vibrators, whereas the Type HVL features two mechanically linked counter-rotating shafts and weight sets and delivers a linear vibration.
