The Blum AVENTOS HF top 22F2800 lift-mechanism set provides the higher power-factor option for two-part bi-fold cabinet fronts, covering LF 10000 to 19300 when used as the supplied pair. Two symmetrical zinc-finished mechanisms are included with positioning pieces and eight 4 × 35 mm chipboard screws for the documented screw-on installation.

This set supplies the spring-powered cabinet-side mechanisms at the heart of an HF top installation. It must be combined with the telescopic arm set selected for cabinet height, the specified hinge and mounting hardware, and the appropriate standard or SERVO-DRIVE cover components.

Select by power factor
Choose the mechanism strength using Blum’s power-factor calculation. For symmetrical fronts, LF is the cabinet height in millimetres multiplied by the combined weight of the upper and lower fronts, including handles, in kilograms. For asymmetrical fronts, use the theoretical cabinet height and the combined front weight in accordance with Blum’s current planning information.

Part 22F2800 covers LF 10000–19300 with two mechanisms. If a calculated application falls within an overlap between mechanism ranges, follow Blum’s recommendation to use the more powerful option and carry out a trial application where required.

What is included?

• 2 × symmetrical AVENTOS HF top lift mechanisms
• Positioning system for the screw-on mechanisms
• 8 × chipboard screws, 4 × 35 mm

Telescopic arms, front and centre hinges, mounting plates, front-fixing hardware, cover caps and all SERVO-DRIVE electrical parts are separate.

Technical attributes

Choose the matching arm set
Pair the mechanisms with the appropriate AVENTOS HF top telescopic arms for the cabinet height:

• 22F3200: 480–610 mm
• 22F3500: 600–910 mm
• 22F3900: 840–1200 mm

For asymmetrical fronts, choose the arm set using Blum’s theoretical cabinet-height method. Do not select an arm only from the overall cabinet height.

Complete the installation

A complete HF top system also requires compatible arms, cabinet hinges, centre hinges with the correct mounting plates, lever-arm adapter plates, front hardware and a cover-cap set. A SERVO-DRIVE installation additionally requires the specified drive, cable, switch, power and SERVO-DRIVE cover components.

Frequently asked questions

Is the correct power-factor range 10000–19000?
Blum’s current catalogue gives the exact range as LF 10000–19300 for the supplied pair. The rounded value of 19000 in the original title was incomplete.

Are two mechanisms included?
Yes. The documented set contains two symmetrical lift mechanisms, a positioning system and eight 4 × 35 mm chipboard screws.

What cabinet height does this mechanism fit?
The mechanism strength is selected by power factor, not height alone. A compatible arm set then covers the required height within the HF top system’s 480–1200 mm planning range.

Does it include telescopic arms?
No. Select 22F3200, 22F3500 or 22F3900 arms separately according to the applicable cabinet or theoretical cabinet height.

Does 22F2800 include BLUMOTION?
AVENTOS HF top provides integrated BLUMOTION adjustment for controlled closing when the complete system is correctly selected, fitted and adjusted.

Can it be used with SERVO-DRIVE?
Yes, as part of a correctly planned HF top SERVO-DRIVE system. No drive unit, electrical parts, switches or powered cover set are included here.
