Drive DeVilbiss CHAD Heavy Duty 50 PSI Compressor

This item requires and Rx or Professional License

The Drive DeVilbiss CHAD® Heavy Duty 50 PSI Medical Air Compressor (Model 18450) is a high-capacity, clinical-grade pressure system engineered to power advanced, continuous-duty respiratory setups. Unlike small, intermittent desktop nebulizers, the 18450 is a medical-grade workhorse built to deliver sustained high-pressure airflow ranging from 0 to 50 PSI and an expansive air output of 11 to 41 Liters Per Minute (LPM). This specialized output profile makes it the primary clinical standard for driving large-volume nebulizers, heated humidification networks, mist tents, pediatric respiratory enclosures, and continuous tracheostomy (trach) masks.

At the core of the 18450 is a premium, oil-free WOB-L® piston pump mechanism. This unique technology significantly reduces operational friction, ensuring the delivery of clean, uncontaminated medical-grade air while suppressing acoustic output below 60 dBA. The high-velocity pressure head easily handles hypertonic saline or viscous (thick) medications, breaking down liquid therapies into ultra-fine aerosol particles of 2 microns or less for deep, targeted bronchial deposition. Housed in an impact-resistant composite cabinet, the device includes a built-in metal pressure gauge, an adjustable pressure-locking regulator knob, and heavy-duty vibration isolation mounts to prevent table-surface drift during continuous operation.

Design & Functional Features

• Oil-Free WOB-L® Piston Design: Provides clean, safe medical air entirely free of hydrocarbon mist while dramatically lowering vibrations and mechanical wear.

   

   

• Dynamic Locking Regulator Knob: Features an integrated, pull-to-unlock black control dial that lets providers lock the output pressure seamlessly into the exact prescribed therapeutic window.

• Integrated Pressure Monitor: Outfitted with a professional-grade, analog mechanical gauge on the front face for real-time monitoring of active line resistance and output pressure.

• Continuous-Duty Capabilities: Engineered with a heavy-duty cooling fan and a manual electrical overload reset button, allowing the machine to safely run 24/7 without thermal shutdown.

Product Specifications & Identification

Important Product Characteristics

• System Component Isolation Notice: This unit is a medical air compressor source only—it does not include a nebulizer bottle, tubing, or masks. It acts as the pneumatic driver for clinical accessories such as large-volume all-purpose nebulizer jars or tracheostomy mist collars.

   

   

• Dual Filtration Safeguards: Outfitted with an external foam cooling fan filter on the rear panel and an internal intake filter disc. The rear fan filter can be washed weekly with mild soap, but the internal air intake filter must be swapped out for a new one whenever it shifts to a dull gray color (do not wash or reuse the internal white filter).

   

   

• Application Notice: The 18450 is a restricted, prescription-regulated Class II medical device. It must strictly be set up and calibrated to the precise PSI levels ordered by a physician. It is explicitly not rated to drive mechanical ventilators or anesthesia circuits.

   

  Frequently Asked Questions (FAQ)

  Do I need a prescription to sell or purchase the Drive 18450 Compressor?

  Yes. The FDA classifies all high-pressure medical air compressors capable of continuous output up to 50 PSI as Class II Prescription Devices. Because this unit is used to vaporize medications or drive continuous airflow directly into sensitive respiratory paths (like tracheostomies), you must hold all checkout transactions on your store until a valid provider's prescription is submitted and verified.

   

   

  What is the purpose of pulling out the ring behind the pressure knob?

  This is a built-in safety locking feature designed to prevent accidental setting changes. The black regulator control knob on the front panel will lock firmly in place. To change your pressure, you must first pull the inner locking ring out toward you. Once unlocked, rotate the knob clockwise to increase the PSI or counterclockwise to lower it, then push the ring back in to lock it.

   

   

  Why is this machine so much heavier than a standard desktop nebulizer?

  Standard home nebulizers are built with small, plastic-diaphragm motors that overheat if run for more than 20 minutes at a time. The Drive 18450 weighs 17.2 lbs because it houses a heavy-duty, cast-aluminum piston assembly and an industrial-grade electric motor. This structural mass is necessary to consistently pump high volumes of compressed air indefinitely without pressure drops or overheating.

   

   

  Can I submerge the machine or flush the lines if it gets dirty?

  No, never. The 18450 is an electrical air pump; getting water inside the housing or into the outlet port will instantly ruin the internal vacuum valves and void your warranty. To clean the device, simply wipe down the smooth outer plastic cabinet with a lint-free cloth dampened with a mild household disinfectant or isopropyl alcohol.

   

  Compliance Standard:

  FDA Class II Medical Device Regulations (21 CFR Part 807)

  To ensure strict compliance with current Food and Drug Administration (FDA) regulations, EnhDme enforces a rigorous prescription verification policy for specific restricted medical devices. Because federal law restricts these devices to sale by or on the order of a licensed healthcare provider, orders containing prescription-regulated equipment will remain on a compliance hold and will not be dispensed until a valid prescription is successfully received and verified by our compliance team.
