What is Flexineb E3?

Nortev's Flexineb E3 is a simple to use, silent and portable equine nebuliser system without the standard compressor, hoses, wires and typical inconveniences of old horse nebulisers. The Flexineb E3 is a revolutionary equine nebuliser that enables delivery of nebulised drugs and natural therapies directly to the airways of the horse. It operates from a rechargeable battery and has a unique blue flexible mask interface with a clear aerosol chamber and medication cup.

Why use Flexineb E3?

Respiratory problems in horses are frequently the cause of poor sportive performances. The most frequently occurring lower respiratory tract disorders are Recurrent Airway Obstruction (RAO) also known as Heaves, Chronic Obstructive Pulmonary Disease (COPD), Inflammatory Airway Disease (IAD) and Exercise-Induced Pulmonary Haemorrhage (EIPH) also known as Bleeding. Typically, their treatment includes systemic administration of drugs using injections or the oral route, however administration via inhalation through horse nebuliser masks and inhalers are now considered to be a viable alternative way to treat respiratory disorders (including breathing, airway or lung problems). Nortev's Flexineb E3 is an easy-to-use delivery device that produces a very fine mist of aerosolized drug or natural therapy solution enabling this method of treatment for the horse.

What drugs can be nebulised with your device?

Some examples of drugs that have been successfully nebulised using the Flexineb E3 are: — Antibiotics — Corticosteroids — Bronchodilators — Mucolytics Please note the viscosity of the drug will affect the nebulisation rate and delivery time. To overcome this some drugs can be diluted with saline solution to increase the nebulisation rate and delivery time. To overcome this some drugs can be diluted with saline solution to increase the nebulisation rate, or nebulised with our Green Coded Medication Cup. Please note the following are NOT to be nebulised with Flexineb and may damage the medication cup: AZIUM, VET ONE DEX, VEDCO DEX, DUPHACORT, RESPRADIL, VETADINE, BROMINE, MILTON / BLEACH, COLLOIDAL SILVER, DE-IONISED WATER, IONISED WATER.

What size masks are available?

There are three Flexineb E3 Mask sizes available: -Foal/Pony Size: will fit sizes from foals/small ponies to yearlings. -Thoroughbred Size: will fit 2 year old Thoroughbred to large Warmblood breeds. -Large Size: will fit the largest of horses.
Check out our Size Guides for more details.

My vet has no experience of the technology, where can I get advice on drug dosage?

Nortev can provide this information on request to veterinarians only, including scientific data on nebulisation. Your veterinarian can contact us directly via

Can I mix different medications in the Med Cup and nebulise them together?

Yes you can, but based on our experience, it is better to stagger treatments to gain the full benefit of nebulisation treatment. Example: If your horse is suffering for an infection that is also causing inflammation, from information gathered worldwide from various veterinarians the protocol for treatment would be as follows: Step 1: Nebulise a Bronchodilator, this will help to "open" up your horses lungs. Allow to take effect for at least 10 minutes. Step 2: Nebulise a Corticosteroid, this will help to reduce inflammation within your horse's lungs. Allow to take effect for at least 10 minutes. Step 3: Nebulise your Antibiotic, this will help fight the infection. Repeat as recommended by your veterinarian.

Can I use a Metered Dose Inhaler with the Flexineb E3?

Yes, remove the nebuliser and rotate the clear aerosol chamber to the horizontal position. Insert the supplied Metered Dose Inhaler Adaptor into the top of the aerosol chamber. The Metered Dose Inhaler can then be inserted and actuated into the aerosol chamber. Refer to the User Manual page for more information.

What is the difference between a Flexineb E3 MDI System and a standard Flexineb E3 System?

The Flexineb E3 MDI System only contains the Mask Assembly which will only allow drug delivery by Meter Dose Inhaler (MDI). It does not contain the Electronic Controller, Cable and Medication Cup which is required for nebulisation of a wide range of drugs. The standard Flexineb E3 system includes all system parts to allow both MDI and nebulisation treatments for you horse. With the full system you have the ability to deliver a broad range of medications and natural therapy solutions.

Where can I find information on the benefits of Nebulisation and Aerosol Therapy?

Aerosol therapy offers the benefit of delivering nebulised medication directly to the site of infection in the airways of the horse rather than going indirectly to the problem by delivering the drug orally or by injection. Please check out our Information page on the benefits of Aerosol Therapy.

What is different about the Flexineb E3 compared to other equine nebulisers on the market?

The Flexineb E3 is portable, easy to use, easy to clean and disinfect; it's silent, fast and doesn't waste drug. The distance between the nebuliser and the horse's respiratory tract is short. It's also well tolerated by the horse.

Do you have support from Veterinarians?

Yes, Flexineb E3 was designed with extensive input and support from equine veterinarians in Ireland, United Kingdom, France, Germany, Australia, Canada and United States.

What arrives when I receive a Flexineb E3? Are extra parts required before I can use it?

The Flexineb E3 system contains everything needed to start nebulising and treating your horse.

Do you supply Medications or Solutions which I can use immediately?

Medications are not supplied with Flexineb E3 as these must be prescribed by your vet. The system is supplied with a bottle of 0.9% Saline Solution for immediate use. This helps become familiar with how it operates and to introduce your horse to the system before using it with medications.

What operating time will I get from a fully charged battery?

Operation time is approximately 6 hours from a fully charged battery.

How do I Clean and Disinfect the Flexineb E3 parts?

Please refer to the User Manual for cleaning instructions.

Do you have testimonials and/or references from customers who already use the Flexineb?

Yes, please refer to the Testimonial section of our website for testimonials from a broad range of Flexineb E3 users.

Are there clinical studies completed with the Flexineb E3?

Yes, please refer to the Scentific Studies page for studies carried out with Flexineb E3. Click here.

What is the life span of a Flexineb E3?

The Flexineb E3 system is robust but you must take care of it if you want trouble free use. Always stay with the horse during use, clean it regularly and store it safely away from freezing temperatures and damp conditions. Like all electro-mechanical devices it has some wearing parts which can wear out or become damaged during use. For example, the Medication Cup is a replaceable part and its life is very dependent on the drugs nebulised and how well maintained it is between uses. Typical life of a Medication cup with 0.9% Saline is 150 x 10mls however this can be reduced if many different drugs or natural therapies are nebulised in the same cup or if the cup is not cleaned regularly. The rechargeable battery will eventually require replacement depending on usage and number of charge / discharge cycles.
