In an increasingly competitive market, products manufactured must meet the highest quality standards as even the slightest traces of oil or contaminants can result in polluted product batches and the risk of health hazards for consumers.
Whether you’re dealing with dairy or crisps, beer or water, compressed air that comes into contact with food and beverage must be controlled in accordance with ISO 8573-1 and ISO 12500.
The second a product leaves the production line; the countdown begins on the products lifespan for sale and consumption. Nitrogen is the most cost effective and efficient industry solution for a company’s packaging needs to maintain freshness, increase shelf-life and reduce risk of contamination.
Do you know what’s in your food? We can assure you that consumers won’t want a side of oil with their product, whether it be cheese, coffee or chocolate. Oil-free technology reduces the risk of contamination and provides ISO 8573-1 Class 0 Compressed Air, so you can focus on what matters – making your food the best on the market!
Oil free air can also be achieved in systems that have oil lubricated compressors installed. Depending upon the class of air required Direct Air can advise on how oil free air can be delivered to your system.
If the compressed air system has not been designed for your industry specific requirements, it has potential to cause major problems including spoiled products and unplanned downtime. We offer advice about your current compressed air system and provide solutions to achieve the quality you require.
The International Organisation for Standardisation (ISO) sets three such standards, ISO 8573, ISO 12500, and ISO 7183.
Which standards you should apply will depend on the specific contaminants your aim to remove and the purification equipment you will rely on to do so. Compressed air typically has three main contaminants which are water, particles and oil.
At Direct Air, we offer advice about your current compressed air system and provide quality solutions to ensure you achieve the air quality your business requires. To achieve the stringent air quality levels required for today’s modern production facilities, a careful approach to system design, commissioning and operation must be employed.
Absolutely! And there are multiple benefits that come with generating your own nitrogen on site as opposed to having liquid nitrogen delivered to site…
Direct Air are experienced in providing Nitrogen generation equipment for many industrial applications. Here are a few examples:
Residual oxygen within a package promotes bacterial growth and oxidation, which can compromise quality and shelf life. Using nitrogen minimises the levels of oxygen present, therefore preserving quality and improving shelf lie. This is particularly relevant to coffee processing, meat packaging, dried foods processing and lettuce packaging.
Using a nitrogen blanket during beverage storage, pre and post bottling, prevents the growth of bacteria and other microbes. Another use is purging air from pipes and hoses prior to bottling and to ensure oxygen is not introduced during transport. It can also help to preserve taste and freshness.
Oil free compressors are the perfect solution for applications requiring the highest air quality, resulting in oil-less air for your end-product and production processes. Air purity is critical for many applications where even the smallest drop of oil can cause product spoilage or damage the production equipment, resulting in potential unplanned downtime.
Many manufacturers in critical applications industries choose ISO 8573-1 Class Zero oil-free compressors that provide clean, 100 percent oil-free air. However atmospheric conditions can lead to oil vapour being present in the air generated from an oil free air compressor. Therefore, additional filtration may be necessary for the system as a whole or point of use depending upon the application.
There are many options available to ensure your production runs smoothly and to industrial standards, and Direct Air are happy to advise on what would be the ideal solution for your circumstance. Direct Air can advise on the most suitable means to deliver an acceptable level of oil free compressed air from your existing or new system.

Cotswold Brewing Company are enjoying savings of over £5,000 a year after stopping purchasing nitrogen thanks to new compressed air equipment supplied by Direct Air & Pipework…
Twisted Barrel Ale Brewery and Tap House originally described themselves as ‘the UK’s first Pico-brewery’ brewing on 60L kit, creating just 120 bottles a time. Shortly after this, they realised they’d very much outgrown their set up and relocated to their 5 times larger current site in Fargo Village, Coventry, in 2017…
Located in the heart of Oxfordshire, The Winery at Hundred Hills produces high quality English sparkling wine. The Winery at Hundred Hills know all about winemaking but needed to know more about their compressed air options. They needed to find a solution to use compressed air to reliably disgorge wines at the end of ageing on lees…
Thatchers have been making cider for over 100 years and as the world around them has changed so have their production lines. The increase in demand for Thatchers quality cider products prompted the Jubilee building project.
Lilley’s Cider is a Somerset based company producing award winning English ciders and perries, established in 2007 by father and son duo, Chris and Marc Lilley.

Itasca Wines is a full contract winemaking facility based in Hampshire and established rather recently in 2020. The English winery provides sustainably driven Grape to Bottle service for it’s customers all across the UK. Itasca Wines built their site from two old barns to a fully operational winery during the summer of 2020, meaning they also required a brand new compressed air set up. They required a system that could reach throughout the entire 1000 square meters of Itasca Wines facility to operate the various applications.
