Where is compressed air used in glass manufacturing?

Compressed air is used across several areas of glass production. It can power forming and drilling equipment and support processes such as glass blowing, conveying, clamping, cooling, molding, mixing, blending, and cleaning. This makes a reliable air supply important for day-to-day plant operations.

Why does a glass forming machine need a reliable air supply?

A compressed air glass forming machine depends on pneumatic components to carry out repeated movements during production. If the air supply is unstable or contaminated, valves and cylinders may not operate properly, which can affect equipment performance and interrupt production.

How can moisture in compressed air affect glass quality?

Moisture can interfere with glass processing and may lead to problems such as inconsistent glass homogeneity, uneven toughening, fogging, and reduced glass strength. Controlling moisture is therefore an important part of maintaining consistent production quality.

What does Delair offer for compressed air treatment in glass plants?

Delair provides industrial air dryers for glass manufacturing, including refrigeration and adsorption dryers, along with pre-filters, Fine Filters and oil filters. The dryers help remove moisture from compressed air, while the filters help remove oil, dust, and other solid contaminants before the air is used in production.

Use of Compressed Air Dryer

Compressed air is required in healthcare facilities to operate:

Surgical instruments such as saws and pneumatic drills like bone drilling
Life support equipment like ventilators
Respiratory therapy apparatus
Hyperbaric chambers
Pneumatic tools for dental surgery
At times, as a carrier gas in anaesthesia in place of oxygen, which is very expensive.

Moisture Problems

Few process control applications are as critical as installing and maintaining the systems that deliver vital, life-sustaining medical air to hospital patients. Moisture (Condensation or water vapour) in the Compressed air stream leads to valve clogging, operation failure, equipment malfunction, and corrosion, thereby increasing downtime and the maintenance cost of Pneumatic controls. Moisture-laden Compressed Air also leads to problems like clogging of neonatal ventilators and seizing of surgical drills.

Dry, quality compressed air is an absolute must for healthcare applications.

The Delair Solution

The only positive means of moisture removal from the compressed air stream is the installation of an air dryer. Water vapour can be economically removed by two methods: cooling the air and adsorption.

Delair offers a wide range of both refrigeration dryers and adsorption dryers for all your needs.

For general plant and instrumentation air where the requirement is between 3°C PDP and 6°C PDP, Delair refrigeration dryers – FDI Series do the job.

If the application requires extra dry air and PDP below 2°C, Delair adsorption Dryers—DC Series and engineered systems are relevant.

Frequently Asked Questions

1. Where is compressed air used in hospitals?

It powers surgical tools such as bone drills and saws, dental pneumatic tools, respiratory therapy equipment, and hyperbaric chambers.

2. How does moisture affect hospital compressed air systems?

Condensed moisture can clog valves, corrode pneumatic controls, and cause surgical drills to seize. This increases downtime and maintenance costs.

3. Which Delair dryer suits hospital applications?

Refrigeration dryers (FDI Series) suit general plant and instrument air. Desiccant dryers (DD/DC Series) suit applications that need much drier air.

4. Do Delair dryers follow compressed air quality standards?

The 2025 brochures reference ISO 8573-1:2010.

5. Can Delair dryers be used for medical breathing air?

Medical air used in ventilators is treated as a pharmaceutical, and its production and distribution in hospitals is governed by ISO 7396-1. European Pharmacopoeia limits moisture to 67 ppm v/v, which is about -46°C atmospheric dew point.
