ATMOS E 341 and C 341 Battery: Emergency Suction Ready for the Crash Cart

ATMOS E 341 and C 341: what is the difference

The two models share the same housing concept and battery design but differ in how vacuum is set. The E 341 uses preset electronic vacuum values, which suits emergency use where speed and repeatability matter and staff should not have to adjust a dial. The C 341 offers infinitely variable vacuum, which gives more flexibility on wards and in settings where different patients need different levels.

Published capacity is 34 l/min for the E 341 and 26 l/min for the C 341, with a vacuum range of 0 to −800 mbar. Battery operation is listed as 1 h for the E 341 and 0.75 h for the C 341, and weight as 3.65 kg and 4.6 kg respectively. The dimensions are 277 × 370 × 146 mm (height, width, depth).

Readiness: automatic function check and LED indicator

An emergency unit is only valuable if it works the first time. The ATMOS units include an automatic function check and an LED vacuum indicator, so the state of the unit is visible without special tools. The housing is tilt-resistant and shockproof, which matters on a moving trolley or in an ambulance bay.

The battery can be replaced without tools, which shortens downtime. Build a routine in which the unit is kept on charge, checked at the start of each shift and recorded on the crash-cart checklist.

A practical routine is a weekly check recorded on the crash-cart log: switch on, occlude the tubing, confirm the vacuum indicator and note the battery state. After any use, clean the unit, replace the canister and filter, and put it back on charge so that it is never left half-ready.

• Tilt-resistant, shockproof housing
• Tool-free battery replacement
• Vacuum range 0 to −800 mbar

Mounting: wall, rail and one-handed release

The units mount on a wall or on a standard rail of an emergency trolley and can be released with one hand. This allows the unit to travel with the patient during in-hospital transport while the other hand remains on the airway or the stretcher.

Check the rail dimensions of your trolleys before ordering and decide where each unit will live. A unit stored in a cupboard is rarely used in time, so mounting on the trolley or wall near the bed is recommended.

Where battery emergency suction is used

Typical locations are resuscitation trolleys, emergency departments, ICUs, wards, recovery areas, radiology and in-hospital transport routes. Because the units address patients from neonates to elderly, vacuum selection and catheter size must follow your clinical protocol; our guide to neonatal suction discusses the special case of newborns.

For the wider picture of selecting a battery unit, read the battery emergency suction guide. If you want a mains-powered portable device with larger canisters for the OR and wards, compare it with the ATMOS C 451. The unit is shown on the E 341 / C 341 Battery product page.

Plan the number of units around areas rather than patients: one per resuscitation trolley, one per recovery bay and a small pool for transport. This avoids borrowing devices from neighbouring wards in an emergency.

Selection checklist and next steps

When choosing, check the run time against your longest realistic scenario, the vacuum settings available, canister and filter compatibility, charging arrangements and spare battery cost. Ask which standards the manufacturer declares for suction equipment, for example under ISO 10079, and request the declaration of conformity.

Confirm registration status in the UAE and any facility conditions. Beckfinity can supply the units with delivery and staff training; contact us for a quote or consultation on your emergency suction plan.
