Industrial blowers typically tagged "59 URAI" or with similar designations have important jobs to do. They help circulate air, push industrial gases along through the plant, vent machines that may have too much internal pressure,  and/or speed-dry products in a "hot room."  Often, these blowers have specific designs made to support the intake and exit ports of the equipment to which they are attached. Five industrial blower designs by type are listed below.

Horizontal

Horizontal blowers look like flat, low tables. They are squat, with feet you can bolt to the concrete floor in your plant. Their in/out ports are located on the bottoms/tops of the blowers and straight through the middles of the devices. They are ideal for ceiling mounts, wall mounts, or anywhere where pipes come up through the floor.

Vertical

Vertical blowers essentially take horizontal blowers and turn them on their sides. They are a little more barrel-shaped, and they still have "feet" to secure them to the floor (or other solid surface). The ports are still straight through the center, except that vertical blowers are idea for horizontal pipes running above ground.

Right Hand Orientation

Right hand orientation blowers send air or gases to the right, when you are standing and facing the installed or ready-to-install blower. This may seem strange, considering that most people think a blower can blow right or left without needing to specifically face one direction. However, the internal positive airflow components are built in such a way that you cannot simply turn the blower one-hundred-eighty degrees and have it work the same way; it will not. Right hand orientation blowers are made for pipeline connections that send air or gases to the blower from the left.

Left Hand Orientation

Likewise, left hand orientation blowers cannot turn around and be used as right hand orientation blowers. The fan blades inside are designed to forcefully push air in a specific direction. Ergo, a left hand orientation blower can only push and blow air and gases coming through the blower from the right. Which blower orientation you choose all depends on how the pipelines in your plant are laid out and the directions in which air and gases are supposed to flow.

Centrifugal

Centrifugal blowers operate in almost the exact same way as leaf blowers. Air or gases are pulled in, spun around, and spit it another port. These blowers are ideal for tight spaces where pipes cannot effectively meet without a dual-port blower.
