JetSpray compressed air & water spray humidifier

The JetSpray provides very accurate humidity control directly to a room's atmosphere using a combination of compressed air and water. A series of strategically located nozzles provide consistent humidity throughout the space.

The use of compressed air ensures very rapid moisture evaporation, without the risk of wetting or drips, and highly directional spray aerosols.

The JetSpray is available in 60L/h and 600L/h capacity models. The 600L/h model is available with on/off control or fully modulating 0-100% output for highly accurate +/-2%RH humidity control.

Self-cleaning nozzles enable the humidifier to work with any potable water quality without the need for a demineralised supply. Its fan-free design ensures robust operation in dirty, dusty industrial environments with minimal maintenance.

The JetSpray nozzle contains a self-cleaning mechanism that prevents blockages. Installation is easy and can be carried out by any competent HVAC contractor without the need for special tools. It incorporates standard plumbing fittings and can be supplied with stainless steel, copper or plastic pipework.

Akubra Hats

Ron Palin

General Manager Operations

“The Condair JetSpray is maintaining the ideal humidity of 70%RH in Akubra’s forming room. This significantly reduces imperfections in the felt, helping to deliver the highest efficiency and quality throughout the hat making process.

It is critical to maintain the relative humidity at 70% in the forming room to prevent any imperfections in the felt during this process, faults which will only show up later in the finishing process stages.”

Aston Martin

Alan Darrock

“We need a reliable, effective humidification system to ensure that we can achieve the utmost finish to our cars. Since the new equipment was installed we have seen improvement in the quality of the paint finish, and our workforce now keep the doors closed. We have been more than pleased with the service and skill that Condair offers and will be using them in other production areas.”

ICS Cool Energy

Malcolm Edwards

Group Technical Manager

“The JetSpray has been in operation now for a number of months keeping the humidity well over the required 90%RH and maintaining a very low 0.67% weight loss. The energy and water savings are a bonus and economies will also be achieved through its easy maintenance programme. All in all, our client could not be happier, and neither could we.”


Mukesh Saxena

Chief General Manager of Fabric Operations

“The JetSpray is maintaining the ideal humidity of 60%RH in Auro Weaving’s warping section. This significantly reduces the generation of fly and yarn breakages, helping us to deliver the highest efficiency and quality in the department. Since we installed the JetSpray humidification system, the ambience of the area is very comfortable and clean. We would highly recommend the JetSpray for humidification in warping and yarn storage, where reliable and accurate humidity control is essential.”

VMT Spinning Company

Gurpreet Singh

Unit Head

“The JetSpray has proved highly suitable for our requirements. It consistently maintains the required relative humidity in the area and has very hygienic operation.

It is a sealed system with no circulation of water, so there is no scope for growth of micro-organisms. It is also user friendly and practically maintenance-free.”

John Watson & Co

Chris Fyfe

Quality Assurance Manager

“When paper loses moisture, ink will not adhere properly, which could cause a problem for our printing company whose reputation for quality is high. Not only has the JetSpray been proven in our industry, it is also uncomplicated, energy efficient and extremely hygienic in operation.

Due to the conditions in our print room, the humidifier has been running 99% of the day since installation, keeping RH at a perfect 50%.”


Steve Freeman

Jet Press Solutions Manager

“Humidity control is important for paper handling consistency when running lighter weight stock on the Jet Press 720S in both the feeder and jetting area. We aim to maintain an RH of between 40% and 60%. Below this could potentially cause an increase in paper handling issues on light weight paper.

Once the humidifier was up and running correctly, it has performed well. It now easily and quickly gets the room up to the required RH and maintains this after start-up.”

Parmeshwari Tea Company

Ajay Dhandharia

Managing Partner

“After installing the JetSpray system we observed that any level of humidity required is constantly achievable without condensation or water getting deposited on the floor or over the machine. With improved humidity conditions, teas became brighter, blacker with better bloom and improved density.”
