Speed-Guardian™ 4000 A Acoustic

Acoustic Model with Circular Guide Track

The panel is securely guided into a spiral bracket without any contact between the two. With a high performance frequency converter control box and the chain mechanism with spring compensation, the door reaches an opening speed of up to 80" / second.

Acoustic Panel Insulates Sound Up to 31 dB

For special applications that require acoustic insulation for sound-deadening, the Speed-Guardian™ 4000 A high speed door has a 1-5/8" thick panel made of smooth C0 anodized aluminum with aluminum hollow profiles. The hollow profiles are filled with 5 mm PVC and 30 mm PU-foam, providing acoustic insulation up to 31 dB.

Smart Start™ NXT NEMA 4X UL Control Box - Standard

All 5000 models include our Smart Start™ NXT, NEMA 4X UL, control box as standard.  A distribution block accepts the activation and protection device wiring; main power cables feed through pre-drilled holes on the bottom of the box where the individual wires, with pre-wired removable terminal blocks, simply plug into the circuit board.  There are extra ports on the control board allowing for firmware upgrades and future expansion.  A USB port is included for maintenance monitoring.

Built-in Light Grid

The standard light grid is integral with the guide tracks making it less susceptible to damage by passing loads.  This system enhances protection of personnel and goods and drastically reduces the likelihood of damage and repair to other parts of the door, saving on maintenance costs.

R-value refers only to the panel's resistance against energy loss. U-value is an internationally recognized measurement tool that provides data about the energy flow lost through the total panel construction including the panel, seals, windows, etc. The 5000's solid sections provide the most efficient U-value available today.
