ATMOS Record 55 Surgical Suction Unit: Specifications and Selection Notes

ATMOS Record 55 performance in numbers

The published data for the Record 55 are a suction capacity of 55 l/min, a maximum vacuum of −98 kPa (−980 mbar) and a noise level of 39 dB(A). The unit weighs 24 kg and measures 940 × 500 × 390 mm in height, width and depth, so it is a mobile floor-standing device rather than a handheld one.

Two powerful diaphragm pumps give fast vacuum build-up. Diaphragm pumps are oil-free and do not need regular pump oil changes, which suits operating-room hygiene routines. A noise level of 39 dB(A) matters in an OR where the team communicates continuously and where monitoring alarms must be heard.

Controls, gauge and safety features

The Record 55 has intuitive controls, an adjustable vacuum and a clear vacuum gauge, so the vacuum level can be checked at a glance even under pressure. Smooth housing surfaces ease cleaning between cases.

A hydrophobic bacterial and viral filter protects staff and patient and helps prevent fluid from reaching the pump. Always confirm the replacement interval and the filter part number with your supplier, and keep spare filters in stock so that a blocked filter never takes the unit out of service.

A simple daily routine keeps the unit dependable: before the first case, occlude the tubing and confirm that the vacuum rises to the expected level and holds; inspect tubing and connectors for cracks; check that the filter is dry and clean. Record the result so that deviations over time become visible to your biomedical team.

Canister systems: Direct Docking or standard rail

The unit is available with the Direct Docking System, where canisters attach directly to the unit, or with a standard rail for disposable canister systems. Direct docking gives a compact, stable assembly and fewer loose tubing connections. Disposable systems reduce handling of contaminated fluid and cleaning work, but create waste cost.

Choose according to your sterile-processing capacity and your waste policy. For related choices, see our guide to suction canisters, tubing and filters.

• Direct Docking System: canister mounted directly on the unit
• Standard rail: for disposable canister systems
• Hydrophobic bacterial and viral filter on the suction line

Where the Record 55 fits among surgical aspirators

With 55 l/min of flow, this high flow surgical suction unit suits general and orthopaedic surgery, and operating rooms that need fast evacuation of fluids. If your cases demand continuous high flow with a rotary-vane pump, compare it with the MEDAP TWISTA SP 1070. The trade-offs between pump types are explained in diaphragm vs rotary vane suction.

To understand why both vacuum and flow must be specified, read our suction pressure and flow settings explainer. The overall product group is covered in the surgical suction unit guide and on the ATMOS Record 55 product page.

In practice, a unit of this class is often placed as the main mobile aspirator of a theatre, with a second smaller unit held as backup. Think about where the device will stand relative to the table, the anaesthesia machine and the electrosurgical tower, so that tubing does not cross walkways and the gauge stays visible to the circulating nurse.

Questions to ask the supplier

Ask how fast the vacuum builds to a working level with your canister size, what overflow protection is fitted, how often the diaphragms need service and who provides it locally. Request the cleaning and disinfection instructions and check that they match your OR protocols.

Confirm the device registration status in the UAE and any facility conditions. Beckfinity supplies and supports ATMOS equipment, including maintenance; contact our team for a quote or consultation on your suction plan.

Finally, ask about training. A short in-service for scrub and circulating staff on assembly, the correct filter position and what to do when the canister fills prevents most avoidable faults.
