HMU Frameless Ultra-High Efficiency Particulate Air (ULPA) filters are primarily used in the electronics and pharmaceutical industries, cleanrooms, laminar flow equipment, and other applications requiring ultra-high cleanliness.

The filtration efficiency for particles ≥0.3μm is over 99.9995%.

The filters are folded using a computer-controlled fully automatic folding system with adhesive spraying; the folding height is infinitely adjustable from 22 to 96mm.

Ultra-fine glass fiber filter paper is used as the filter media.

Each filter undergoes rigorous testing.

Standard sizes are used.

The F-type is a knife-edge type for liquid tank sealing.

Separatorless Air Filter

Dongguan Youte Purification Technology Co., Ltd. is a technology-based enterprise engaged in the research, development, production, and sales of purification equipment, air filters, air showers, pass-through windows, air outlets, clean booths, laminar flow hoods, negative pressure weighing hoods, and other purification equipment. Main products include: dry liquid tank type high-efficiency air outlets, integrated air outlets, FFU fan filter units, air showers and cargo showers, clean booths, clean workbenches, pass-through windows, primary and medium-efficiency filters, separator-type and separatorless high-efficiency filters, liquid tank type high-efficiency filters, high-temperature resistant filters, and other purification equipment.

An air filter is an air filtration device, generally used in cleanrooms, clean factories, laboratories, and clean rooms, or for dust prevention in electronic, mechanical, and communication equipment. 

There are pre-filters, medium-efficiency filters, high-efficiency filters, and sub-high-efficiency filters, among others. Different models have different standards and performance levels.

In pneumatic technology, air filters, pressure reducing valves, and lubricators are called the three main pneumatic components.

 To achieve multiple functions, these three air source processing components are often assembled together in sequence, called a pneumatic triplet. It is used for air purification and filtration, pressure reduction, and lubrication.

The installation sequence of the three main components, in the direction of air intake, is air filter, pressure reducing valve, and lubricator. 

These three components are the primary air source devices in most pneumatic systems, installed near the air-using equipment, and are the final guarantee of compressed air quality. Their design and installation, in addition to ensuring the quality of the three components themselves, must also consider factors such as space saving, ease of operation and installation, and the ability to be combined arbitrarily.
