Rotary positive blower intake and discharge silencers are twin lobe rotating mechanism for delivering large quantity of air or gas at relatively constant volume for either pressure or vacuum applications. The blower installation is produce excessive noise and destructive pulsations, which can be harmful for the equipment, personnel and the neighborhood. In order to achieve silencing and pulsation control, the silencers at intake and discharge are used irrespective of the blower size and speed.

Rotary Positive Blowers are designed with detachable steel mounting feet to permit in-field adaptability to either vertical or horizontal installation applications. The rotary positive blowers offer vacuums to 16 inch Hg and flows from 100 to 3,350 CFM. This blower is available with the Roots' Whisper plenum to reduce noise and power loss. It features oil splash lubrication throughout, tri-lobe rotors and reduced noise. The blowers are generally interchangeable, with respect to footprint, shaft height and diameters, with equivalent sizes of other blowers, so replacement of existing installations is simplified.

Rotary Pots are produced in ganged form with a single shaft controlling several pot wipers. Rotary pots are used as volume controls in audio equipment and also for controlling the brightness of lamps, the speed of motors and many other purposes. These rotary pots are controlled by dragging the mouse up or down rather than in a circular motion. The rotary pots give instant access to pans, aux sends, plug ins, input-output assignments and channel automation modes. Rotary pots are provided to trim the level of the AFL and PFL busses.

Rotary Pressure/Gravity Fillers provides for reproducible thin-cake, continuous production in a single unit. The filtration is conducted via pressure of up to 90 psig. Positive displacement washing or countercurrent washing follows filtration. The cake is dried by blowing hot or ambient-temperature gas through the cake. This gravity fillers are suitable to fill liquid products into empty or already pre-filled containers.

Rotary Pump is like the reciprocating pump in that it allows a fluid to fill a space that then decreases in volume, forcing the fluid out of the space. Rotary pump includes a casing having a rotator rotatably received therein and a shaft fixedly extends through the rotator.

Rotary pumps operate on the principle that a rotating vane, screw, or gear traps the liquid in the suction side of the pump casing and forces it to the discharge side of the casing. These pumps are essentially self-priming due to their capability of removing air from suction lines and producing a high suction lift. In pumps designed for systems requiring high suction lift and self-priming features, it is essential that all clearances between rotating parts and stationary parts be kept to a minimum in order to reduce slippage. Slippage is leakage of fluid from the discharge of the pump back to its suction.

A rotary rack oven is an industrial grade oven. The rotary rack oven can fit one to two racks of 60cm x 40cm trays and are excellent at baking large volumes. It has conventional and convection types of ovens. These types of ovens are extremely large and expensive and are generally used by large professional pastry kitchens. The convection ovens are great for making cookies or even tart bases and bake savory foods
