LCN 4822 Pneumatic Auto Equalizer Power Operator - Top Jamb (Push Side)

The LCN 4822 is a pneumatic automatic door operator. Pneumatic means pressurized air does the work of opening the door, not an electric motor. An air pump in a separately purchased control box pressurizes a system. Pneumatic tubing carries that pressurized air from the control box to each 4822 unit installed at the doors. When the activation button is pressed, the control box releases a burst of air through the tubing, the 4822 actuates, and the door opens. The door then closes automatically via the mechanical closer mechanism built into the unit.

This is the push side, top jamb mounted version. The unit mounts on the frame head directly above the door on the push side. Non-handed, so it works on both right-hand and left-hand swinging doors without modification. Meets ADA requirements in power mode.

Why Pneumatic: The Multi-Door Advantage

The electric 4631 has its own controller module inside the unit. One door, one self-contained system. That's simple and clean for a single ADA door but gets expensive when a building has five or ten ADA doors that all need automatic operators.

The 4822 pneumatic system works differently. One control box with a built-in air pump powers an entire network of 4822 units through pneumatic tubing. The LCN 7981 single control box handles one door. The LCN 7982 dual control box handles two doors. Each door gets a 4822 unit. The tubing runs through the ceiling or wall framing to connect each unit to the central air source. When a building needs multiple automatic doors, the cost of the air pump is shared across all the doors rather than duplicated at every opening. That's the multi-door advantage of the pneumatic system.

System Components Required

The 4822 operator is the door-side unit only. A complete pneumatic automatic door system requires the following additional components, sold separately:

Control box with built-in air pump: the LCN 7981 for a single door, the LCN 7982 for two doors. For systems requiring a sequential timer, the LCN 7982S adds that function. For systems integrating with an electric strike, the LCN 7981ES or LCN 7982ES includes an ES relay. LCN 925 Pneumatic Tubing connects the control box to the operator at each door.

Activation devices (push plates, wave sensors, or push pads) connect to the control box and signal it to actuate the door.

Confirm all required components before ordering. The 4822 alone does not make an operational automatic door system.

LCN 4822 Pneumatic vs LCN 4631 Electric

Both are LCN low-energy automatic door operators. Both meet ADA requirements. Both eliminate the need for safety mats and guard rails.

The 4631 is electric, 120V, self-contained. One unit per door, no air pump, no tubing. Simple single-door installation.

The 4822 is pneumatic. Requires a control box with an air pump and pneumatic tubing at each door, but one control box handles multiple doors. More components, more initial planning, but more cost-effective when multiple ADA doors are needed across a building.
