General product information only, not medical advice. This page does not describe how to set up or operate suction on a patient; follow the manufacturer’s instructions for use and facility policy.
Short answer
In a hospital or clinic, a vacuum regulator (also called a suction regulator) is the device that connects to a wall vacuum outlet and controls how much negative pressure reaches suction tubing and a collection container. It carries a gauge for reading the set level, and many models offer continuous and intermittent modes. In US regulation it is a Class II device under 21 CFR 880.6740.
Definition and scope: medical versus industrial regulators
The same two words are also used in industrial engineering for process equipment; this page covers only the medical device used with a hospital vacuum pipeline.
The FDA regulation at 21 CFR 880.6740 identifies a “vacuum-powered body fluid suction apparatus” as a device used to aspirate, remove, or sample body fluids, powered by an external source of vacuum. The regulation lists the generic type as including vacuum regulators, vacuum collection bottles, suction catheters and tips, connecting flexible aspirating tubes, rigid suction tips, specimen traps, noninvasive tubing, and suction regulators (with gauge). So the regulator is one component of a larger apparatus, not the whole system.
The Global Medical Device Nomenclature definition recorded in the FDA’s AccessGUDID data, for a “vacuum suction regulator/regulation set, general-purpose”, describes a noninvasive device designed to connect to the terminal unit (wall outlet) of a vacuum pipeline system to control the degree of negative pressure. It allows continuous and/or intermittent suction at variable levels, incorporates a manometer and controls for monitoring and adjusting the level of suction, and may include collection containers, tubing or a stand or mount. It does not include patient-contact devices such as a handpiece, tip or catheter.
How a wall suction regulator is used in practice
The wall outlet is the vacuum source; the regulator sits between that outlet and the rest of the suction line. It does not make vacuum. It limits and meters what the pipeline supplies. Where a room has the pipeline, the outlet is part of the patient-room headwall, alongside the medical gas outlets served by plants such as an oxygen plant.
A manufacturer’s user guide shows what the controls look like. The Tenacore VeeVo 800 and 1500 series (Form L 4.2.3-11, Rev. 4) has a mode selector with three positions: OFF (no flow), CONT (continuous, regulated suction) and INT (regulated intermittent suction), plus a pressure adjustment knob that sets the vacuum delivered. The same guide states that the regulator should always be turned OFF when not in use, which prevents unnecessary operation of the facility’s central vacuum pump and ensures adequate suction for all users.
A regulator is used with a collection container. The same guide cautions that the device must not be used without a collection canister between the device and the patient, and that if the canister has no integral hydrophobic filter, a safety trap or hydrophobic filter should also be used. See the guide to the suction canister for that part of the assembly.
Types: continuous, intermittent and the terms around them
Reading one manufacturer’s specification sheet
The table below is taken only from the VeeVo user guide listed under Sources. Other makes differ, so read the specifications of the exact model.
| Item | VeeVo 800 series | VeeVo 1500 series |
|---|---|---|
| Regulated vacuum range (continuous and intermittent) | 0 to 160 mmHg | 0 to 300 mmHg |
| Relief valve actuates in INT mode | 120 mmHg (plus or minus 10%) | 150 mmHg (plus or minus 10%) |
| Modes | OFF, CONT, INT | OFF, CONT, INT |
| Gauge | Color-coded dual-scale analog gauge, accurate to plus or minus 5% of full scale | |
Continuous and intermittent
Continuous mode supplies regulated suction without interruption. Intermittent mode supplies regulated suction in cycles. The GMDN definitions in AccessGUDID describe both as available “at variable levels” on general-purpose regulators; a separate GMDN term, “tracheal suction vacuum regulator”, is recorded for a Gentec product with a manometer, an optional disposable antibacterial filter, a collection bottle and a mechanical anti-overflow mechanism.
Vacuum regulator, suction regulator and wall suction regulator
The regulation uses both “vacuum regulators” and “suction regulators (with gauge)” inside the same generic type, and the FDA product code KDP is named “Regulator, Vacuum”. In supply catalogs, “wall suction regulator” is the usual phrase for the regulator that attaches to the pipeline outlet, which matches the GMDN wording above. This page treats the three phrases as one device family; the regulation and the GMDN wording do not draw a regulatory line between them.
Where it matters for labs, clinics and supply decisions
- Regulatory identity. openFDA lists product code KDP, “Regulator, Vacuum”, as Class 2 under regulation 880.6740, specialty General Hospital, not an implant and not life-sustaining or life-supporting. A related code, GCX, “Apparatus, Suction, Operating-Room, Wall Vacuum Powered”, is also Class 2 under the same regulation (checked 2026-10-30).
- Class II, special controls. The regulation classifies the device Class II (special controls) and exempts it from the premarket notification procedures in subpart E of part 807, subject to the limitations in 21 CFR 880.9. The openFDA record separately shows the GMP exempt flag as N, so the exemption concerns premarket notification, not quality-system obligations.
- Outlet fittings. The VeeVo guide notes that common outlet fittings include DISS, Chemetron, Ohio and Puritan-Bennett, so a regulator has to match the wall outlet style in use. Gas-side regulators are a different product: see oxygen regulator.
- Prescription labeling. The VeeVo guide carries the statement that federal law restricts the device to sale by or on the order of a physician.
Common misunderstandings
- “The regulator is the suction system.” It is one part. The regulation lists collection bottles, tubing, catheters and tips as other parts of the same apparatus, and the GMDN definition excludes patient-contact tips and catheters.
- “FULL VAC on the gauge is the supply pressure.” The VeeVo guide states that the FULL VAC region of the 0 to 300 gauge does not indicate unregulated vacuum supply pressure; it merely indicates the maximum range of the regulator.
- “It can be left on.” The manufacturer says to turn it OFF when not in use, because it otherwise loads the central vacuum pump.
- “Exempt means unregulated.” The device is Class II. The exemption is from premarket notification only.
FAQ
What is a vacuum regulator?
In medical use, a device that connects to a vacuum source such as a wall outlet and controls the negative pressure delivered to suction tubing and a collection container, with a gauge to read the level. Under 21 CFR 880.6740 it is part of the vacuum-powered body fluid suction apparatus family.
Is a suction regulator the same as a vacuum regulator?
The regulation names both “vacuum regulators” and “suction regulators (with gauge)” in the same generic device type, and the FDA classifies the product code as “Regulator, Vacuum”. Catalogs use the terms interchangeably for the wall-outlet device.
What is a wall suction regulator?
A suction regulator designed to attach to the terminal unit on the wall of a hospital vacuum pipeline, with continuous and, on many models, intermittent modes and a manometer for reading the set level.
What FDA class is a vacuum regulator?
Class II (special controls), product code KDP, regulation 21 CFR 880.6740.
