  • How it Works
  • Description

Flexineb™ is a silent, efficient, portable equine nebulizer device that is simple to use, comfortable and affordable. It operates without the noise of loud compressors or the inconvenience of cumbersome hoses and electrical cords.  

Flexineb™ utilizes proprietary technology and is extremely portable allowing in excess of three hours of operation before the lithium-ion battery needs recharging.


The Flexineb has proven itself useful when nebulizing antibiotics, bronchodilators, corticosteroids and mucolytics. Read the Flexineb™ Drugs Table for medications.

Cleaning and Disinfecting:  

Cleaning is easy. Simply wash with warm, soapy water. Disinfecting is done by using cold sterilization methods. Read more about how to properly clean your Flexineb™ with the Medication Cup Cleaning Instructions.

Volume of Medication:  

A standard 10 milliliter medication cup is included. A 20 milliliter extension is provided to facilitate volumes of up to 30 milliliters. No medication remains wasted in the cup after treatment.

Comfort and Tolerance:  

Flexineb™ fits comfortably onto the horse’s nose as a result of the flexible material. An adjustable regulator allows full control of the exit valve, enabling the caregiver to bypass the valve for easy breathing or to facilitate inhalation of the medication deep into the lungs.


The transparent aerosol-holding chamber allows the user to see the aerosol mist being generated by the Flexineb™ system, in conjunction with the horse’s breathing emptying the chamber and receiving the fine particle aerosol.


System accessories include an AC power supply to charge the internal battery, a 20 milliliter extension cup, a cover plug for cleaning the med cup, a user manual, medication chart and a hard sided case.  

The FLEXINEB controller is set to run for 18 minutes each time the POWER button is depressed.  After this time, if there is still medication to dispense or if you are using the extension cup, you will need to depress the POWER button again to resume nebulizing. 

Although the Flexineb™ mask material is soft and flexible, the front aerosol chamber and battery controller are made of hard plastic. Therefore, caregivers should be mindful of the risk posed by the horse moving its head when the Flexineb™ is fitted on the animal.

The Flexineb E3 Complete Nebulizer System (Adult Size) is a portable, silent, highly effective equine nebulizer that delivers aerosolized medications and natural therapies to the airways of the horse. The soft flexible mask fits over the face of the horse and creates a seal by tightening the strap around the head. Since the battery is rechargeable, the Flexineb unit may be placed on the horse while walking so that deeper respiratory function is encouraged. 

This complete FLEXINEB adult size system provides everything required including: a standard flow Medication Cup, Metered Dose Inhaler (MDI) Adaptor, Aerosol Holding Chamber, Inlet Valve Kit, Exit Valve Kit, Flexineb 2 Controller Kit with safety strap, Battery, Battery Connector Cable, Flexineb 120 Volt Charger System, Mask Strap, Blue Soft Shell Mask, User's Guide and Carrying Case.

Inside mask circumference is 20".

I LOVE my Flexineb

I LOVE my new FLEXINEB. When you said it was quiet. I had no idea it was so quiet you can hardly hear it. I bought it for my horse, SHEZABEE (one of the spookiest horses I know). All the other products out there scared her during the entire treatment. Now she never moves a muscle with when using the FLEXINEB since it is so quiet. This machine is by far the best on out there. It is definitely worth the money. I had to use mine as soon as it arrived! Thank you for making a great product.

Phenomenal Product and Awesome Service!

I absolutely love my Flexineb Nebulizer. It is user friendly, super easy to clean(which was very important to me) quiet and even those nervy horses mellow out quick and really enjoy their treatment. Great for at home use or adding to your business. I would highly recommend this product and Brandenburg equine as a company that provides quality products and above and beyond service. I’m a customer for life.

Gets rid of the annoying dust allergy cough!

Love the Flexineb

I used the Flexineb on Portersize Just a Jiff last summer in the run up to The European Eventing Championships. Jiff sometimes gets a dry cough when he travels a lot and the Flexineb is the best device to get rid of the cough
