The Grams Medical S‑300 aspirator is designed for surgical and cosmetic procedures—especially liposuction and fluid aspiration—where robust vacuum performance and reliability are essential. At its heart lies a two‑stage rotary oil‑type pump module, chosen for its ability to generate deep vacuum (measured in microns) while maintaining lower noise and stable operation. The system is enclosed in a sound‑insulated housing, with a clam‑shell style aluminum chassis that allows quick access to internal components for maintenance (pump, filters) without fully disassembling the unit.

Operational control is dual‑mode: a manual switch on the electrical panel allows the aspirator to be turned on or off directly (bypassing the foot pedal), or it can be operated via the pneumatic foot pedal in a “push on / push off” style. This enables the surgeon or assistant to control suction hands‑free, which is crucial in sterile surgical environments. The foot pedal is pneumatic (i.e., air / vacuum actuated), and care must be taken to press quickly and firmly to engage or disengage suction reliably. A pilot light indicates when the aspirator is active. In the event of overload, an internal circuit breaker can be manually reset from the electrical panel.

In clinical workflow, once powered on, the S‑300 can achieve its rated vacuum level (close to 28 in Hg) within about 12 seconds, making it responsive for intermittent high-demand suction tasks. Fluids and aspirated tissue pass through a disposable container (typically 1.5 L) before reaching filters and the pump, preventing contamination of the pump module. Because vaporized moisture may accumulate during deep vacuum use, periodic drainage and oil servicing are required: the design allows moisture to separate from oil when the module cools, enabling draining after use, while full oil change is scheduled after up to 50 hours of run time. The modular pump can be removed easily for maintenance; hoses detach and the module lifts out, reducing downtime. Taken together, the S‑300 aspirator with its foot pedal control offers a reliable, efficient, and surgeon‑friendly suction system for operative environments.

This medical equipment item is being sold in its current condition, with only a basic assessment performed. It powers up and successfully completes its self-check or boot process, indicating that it is operational to that extent. However, no further testing beyond this initial check has been conducted.
