Product overview

The Laerdal Suction Unit is a portable powered suction system for emergency care. Its robust, splash-resistant construction, one-hand grip and large controls support operation in demanding conditions and while wearing gloves.

The LED panel shows suction and battery status; colour marking identifies the lower suction range used for children and tracheal suctioning.
An integrated device test helps check readiness before use.
Reusable and semi-disposable canister systems can be exchanged to match local workflows.
The rechargeable battery charges on external power and can be replaced in the field without tools; vehicle-power and external-charging options support mobile use.
Components disassemble for cleaning, and canister-specific filters support the selected collection system.
