Whether you manufacture devices for ICU's, Acute Care, Monitoring, Testing, Drug and Vaccine Development or Rehabilitation, Thomas provides pumps and compressors to power your equipment. The breadth of our product portfolio, spread on five technologies and over 100 product series, offers you a component you need. Our flow control solutions along with value engineering and extensive customization, enable you to achieve high efficiency, long-lasting performance while decreasing total cost of ownership and satisfying patients' comfort.

With a reputation for reliability and quiet operation, Thomas products are found in all types of equipment designed to monitor, sterilize, diagnose and analyze. Other applications that use Thomas products assist in healing, promoting a patient's comfort, and supporting life itself. We cover pumps and compressors for applications such as Breathing Support, Hospital Beds, Hematology, Capnography, In Vitro Diagnostics (IVD), Drug Discovery, NPWT or Deep Vein Thrombosis and more.

Breathing Support and Respiratory Therapy

Thomas compressors and vacuum pumps are used in life-saving devices for respiratory therapy such as ventilators and oxygen concentrators. Thomas stationary oxygen concentrator pumps continue to set the standard through development projects with global leaders in the home health care markets. By combining the efficiencies and operating characteristics of AC or BLDC WOB-L® technology with lightweight chassis materials, we are able to meet the challenges of an evolving market for respiratory equipment. 

Mechanical ventilators or respirators blow air or air with increased oxygen through a humidifier that warms and moistens the air that passes through a tube into the patient’s airways. The exhaled air then flows through a tube away from the patient and back to the mechanical ventilator.

A compressor provides auxiliary air supply to the ventilator to allow it to be used in medical facilities that do not have a central air source.

Capnography monitors the concentration or partial pressure of carbon dioxide (CO2) in respiratory gases. This measures the degree of oxygenation and ventilation in both intubated and spontaneously breathing patients.

The concentration of Carbon Dioxide is critical in intensive care or during surgical procedures such as the control of anesthesia gases. The gas diaphragm pump draws exhaled breath from an intubated patient into the patient monitor for continuous monitoring purposes. Air or gas sampling is only effective when an uncontaminated sample is analyzed. That’s why a capnography device relies on a diaphragm pump to transfer a patient’s breath to a sensor for analysis.

Modern, higher end, steam autoclaves (so-called Europe Class) work with pre- and post-vacuum. Before the actual sterilization process the chamber is repeatedly evacuated - in fractionizing steps - with the help of a vacuum pump.

Blood Analyzers

Blood analyzers provide medical technicians time-critical blood analysis information required to make treatment decisions quickly and accurately. These types of analyzers can measure blood properties such as red and white cell count, glucose, drugs, medication, and many others.

Chair Lifts

Chair lifts offer just the right amount of assistance for someone who requires help standing up or sitting down. To stand, the entire chair is gently lifted up and forward. To sit, the same principle is used in reverse.

Dental Carts

Dental carts usually sit beside the patient chair and offer the dentist several tools, for example drills and suction tubes, to perform the tasks required during a routine dental visit. These carts utilize compressed air to activate tools, or vacuum to draw the required air.

Gas Monitoring

Used to determinate the baseline levels of waste anesthetic gases during surgical procedures and also prior to surgery. Testing of breathing zone levels in all OR's, the recovery room and ancillary areas as required.


A nebulizer consists of a nebulizer (mouthpiece) and a compressor. The airflow to the nebulizer changes the medication solution to a very fine mist.

Negative Pressure Wound Therapy (NPWT)

NPWT is a therapeutic technique, that uses air flow to help stimulate the healing of wounds and burns through a film applied on the injury under negative pressure. The suction pulls fluid and infection from the injury. The NPWT device relies on Thomas pumps for a low sound level, extended pump lifetime, and efficiency thanks to brushless DC configurations.

Dialysis Machines

Hemodialysis is a process by which excess waste products are removed from the patient's blood that is drawn through a special created vein in the forearm known as arterio-venous. This process requires the use of a dialysis machine. The blood flows through plastic tubes to the dialyser that is a bundle of hollow fibers made from a semi-permeable membrane. These types of machines require a peristaltic pump.

Aspirators are widely used in the medical industry today and are found in hospitals and clinics as well as doctor's and dentist's offices. Thomas integrated Diaphragm, Rotary Vane or WOB-L® compressors create a partial vacuum which is used to remove fluids, tissue or foreign material from bodily wounds and injuries. High-end aspirators are mostly used in surgical procedures.

Bath Seats

The chair is designed to allow easy access in and out of bathtubs for handicapped or mobility impaired people. A strong, comfortable and lightweight molded plastic chair seats in the tub and lowers and lifts by means of a bellows that is inflated by compressed air.

Blood Pressure Monitors

In clinical intensive care units a patient's vital signs need to be monitored at least every 15 to 30 minutes. This is accomplished with patient monitors which typically display the patient's heart rate, body temperature, respiration rate and blood pressure. A miniature compressor is responsible for inflating the cuff at the beginning of each blood pressure measurement.

Compression Therapy

The three chambers of the sleeves are filled with air in succession: Chamber 1 to 100%, chamber 2 to 80%, and chamber 3 to 60% of the set treatment pressure. All the chambers remain filled with air until the last chamber has attained the desired treatment pressure. The air is then released simultaneously from all the three chambers, and after an interval the inflation cycle begins once again.

Drug Delivery

These systems are used to dispense medication to patients in liquid form that cannot be taken by means of a pill or injection. They are usually dispensed by means of an IV. They are widely used in hospitals and medical clinics.

Hospital Beds

Pneumatic beds are commonly found today in hospitals and long-term care facilities. They are a must for patients who are confined to a bed long term for the prevention and cure of pressure ulcers commonly called “bed sores”.

Dynamic pressure redistribution is achieved by alternately inflating and deflating the mattress’ individual air cells. The result is superior pressure redistribution across the entire contact area of the body.
