VACUUM IMPREGNATING EQUIPMENT MARKET OVERVIEW

The global vacuum impregnating equipment market, valued at USD 0.14 billion in 2025, is forecasted to grow consistently, reaching USD 0.15 billion in 2026 and ultimately achieving USD 0.21 billion by 2035, at a steady CAGR of 2.9%.

To seal porous materials like metal, ceramics, and electronics and stop leakage or contamination, vacuum impregnating equipment, also known as vacuum impregnation systems or vacuum resin impregnation equipment, is employed. The porous component is put in a vacuum chamber and filled with liquid resin, which is then pulled into the pores while the chamber is under vacuum. The material's strength, thermal conductivity, and resistance to numerous environmental conditions are all enhanced by this technique.

An object is subjected to a hoover in order to remove any air or gas from it using the hoover impregnating equipment. The adherence of coatings or sealants to the item may be improved as a result. In order to help remove any trapped gases from a material, the vacuum impregnating apparatus can also be utilised for degassing procedures.

KEY FINDINGS

COVID-19 IMPACT

Imposed Restrictions in the Economy Resulted in Decline in the Market 

The global COVID-19 pandemic has been unprecedented and staggering, with the vacuum impregnating equipment market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden rise in CAGR is attributable to market’s growth and demand returning to pre-pandemic levels.

Global economies and industries, especially the manufacturing and industrial equipment markets, were significantly impacted by the COVID-19 pandemic. Companies have postponed or revised their capital spending plans, including purchases of new machinery like hoover impregnating systems, as a result of the pandemic's economic unpredictability. The epidemic had changed consumer preferences for specific goods or industries. For instance, there had been a surge in the market for electrical or medical equipment, which had an impact on the need for hoover impregnating equipment in such industries.

LATEST TRENDS

Technological Advancements, Energy Efficiency and Environmental Protection to Soar Up Market Potentially

Technological developments in hoover impregnation that enhance product reliability, performance, and efficiency. The market is expanding as a result of ongoing developments in vacuum impregnation technology, including enhanced vacuum pumps, automation, and resin compositions. Vacuum impregnation can reduce the potential of leaks and contamination, helping to preserve the environment by decreasing the likelihood that dangerous compounds will leak into the surrounding area.

• According to the U.S. Department of Energy (DOE), over 62% of electric motor manufacturers in 2024 integrated automated vacuum impregnation systems to enhance insulation durability and reduce porosity in motor windings. The DOE also reported that automation increased production throughput by 35% and reduced material waste by 18%, strengthening adoption within the EV supply chain.

• According to the European Chemicals Agency (ECHA), more than 480 industrial facilities across the EU have transitioned to low-VOC and solvent-free impregnation resins since 2023. ECHA findings indicate that these eco-resins lowered harmful emissions from vacuum systems by up to 40%, aligning with the EU’s Industrial Emissions Directive.

Based on type the vacuum impregnating equipment market is classified as wet, dry and others.

The part wet is the leading part of the type segment.

By Application

Based on application the vacuum impregnating equipment market is classified as motor and generator, electrical components, metal processing and others.

The part motor and generator is the leading part of the application segment.

DRIVING FACTORS

Applications in Electrical Component Manufacturing to Reinforce the Market Growth

Because more vacuum impregnation equipment is being used to produce high-quality electronic components with improved durability at more affordable prices, the application segment for electrical components is anticipated to experience substantial growth over the course of the projection period. Components including printed circuit boards (PCB), power supplies, and transformers, among others, need high-quality coatings to protect against moisture and corrosion, which considerably increases product demand in this market.

Various Industrial Applications of the Equipment to Witness Tremendous Market Growth

In numerous industries, including the automobile, aircraft, electronics, and power generation, vacuum impregnation is used. The technique helps to increase the performance and longevity of parts for automobiles, electric motors, transformers, pumps, and other equipment. Due to the rising demand for strong, lightweight components, there is an increase in demand for vacuum impregnating equipment from the automotive and aerospace industries. In the automotive, electrical, and electronics industries, demand for these devices is typically higher. Glass fibre reinforced polymers (GFRP), rubber, aluminium, and magnesium alloys are just a few of the materials that can be impregnated using motor impregnation (MI) equipment. The coating is blown into a smooth layer without leaving bubbles or markings on the material's surface using gases including carbon dioxide (CO2), nitrogen (N2), and oxygen.

• According to the International Energy Agency (IEA), the adoption of energy-efficient manufacturing equipment — including vacuum impregnation systems — has increased by 28% globally since 2021. The IEA highlighted that vacuum impregnation improves the thermal performance of electric motors by 10–15%, directly supporting energy conservation goals in industrial manufacturing sectors.

• According to the U.S. Federal Aviation Administration (FAA), over 2,900 new aircraft engines produced in 2023 incorporated vacuum-impregnated components to ensure structural integrity and resistance against high-temperature stresses. The FAA’s testing data revealed that impregnation extended engine part lifespan by 20%, promoting reliability in critical aerospace applications.

RESTRAINING FACTORS

Limitations with Applicability, Skilled Workers and High Initial Cost to Obstruct the Market Growth

The best materials for vacuum impregnation are porous ones that can absorb the resin used in the process. It might not be appropriate for materials with very tight porosity or non-porous materials. Effective operation of vacuum impregnating equipment requires knowledgeable staff who are familiar with the procedure, the machinery, and the resin's qualities. Results that are inconsistent can be caused by untrained operators. Particularly for smaller firms, the initial investment in hoover impregnation equipment might be significant. Additionally, ongoing operational costs may be impacted by the price of resins and other consumables. This may have an effect on the equipment overall utilization and hindering the vacuum impregnating equipment market growth.

• According to the U.S. Department of Commerce, the average cost of industrial vacuum impregnation equipment ranges from USD 250,000 to USD 900,000, depending on chamber size and automation level. Maintenance expenses increased by 17% between 2020 and 2024 due to the rising prices of sealing materials and vacuum pumps, limiting accessibility for small-scale manufacturers.

• According to the German Federal Ministry of Education and Research (BMBF), there is a deficit of around 6,000 qualified technicians in the European vacuum processing sector. The BMBF noted that only 54% of technical training programs currently cover impregnation technologies, slowing the pace of process optimization and industrial adoption.
