4RB Side Channel Blower: One Solution for Global, High-Pressure Air Needs

When you need a blower that works anywhere in the world and handles tough pressure demands, the 4RB side channel blower stands out. Designed for global use and high performance, it offers a smart balance of power, reliability, and simplicity—without the noise and maintenance issues of traditional solutions.

Built for Worldwide Use, Ready Ex Stock

One Blower, No Borders

One of the biggest advantages of the 4RB side channel blower is its true global compatibility. Equipped with 50Hz / 60Hz voltage range motors, IP55 protection, and Class F insulation, it meets major international standards including UL, CE, and CCC.

That means no rewiring, no extra testing, and no modifications. Whether your project is in Europe, America, or Asia, the blower can be installed and used right away. For exporters and system integrators, this saves time, cost, and headaches.

Available When You Need It

Most 4RB models are available ex stock, making them ideal for urgent projects or replacement needs. You don’t have to wait weeks to keep your system running.

High Pressure Difference, Bigger Application Range

Reaching Up to 1000 mbar with Ease

The G400 / 4RB series can reach pressure differences up to 1000 mbar, higher than many traditional gas ring pumps. In the past, achieving this level of pressure meant using larger, louder machines—or systems that wore out quickly.

With the 4RB side channel blower, you get high pressure in a compact design, without internal contact parts that cause wear.

Quiet, Stable, and Smooth Operation

Thanks to its optimized impeller and housing design, the blower delivers:

Low noise levels

No vibration

Pulsation-free air output

This makes it especially suitable for indoor installations and continuous-duty applications.

Designed for Long-Term Value

Oil-Free and Low Maintenance

The 4RB blower produces 100% oil-free air, making it safe for food processing, packaging, and environmental applications. With cooler-running bearings and longer grease life, maintenance is minimal and predictable.

No oil changes. No complex servicing. Just reliable performance day after day.

Compact Size, Easy Installation

Despite its high pressure ratio, the blower keeps a small footprint. Installation is simple, even in tight spaces, and its clean surface design makes it easy to integrate into modern equipment.

One Blower, Many Industries

Flexible for Different Applications

The 4RB side channel blower is widely used in:

Pneumatic conveying systems

Vacuum lifting and holding

Packing and filling machines

Sewage and fish pond aeration

Soil remediation

Thermoforming

Printing, paper, and textile machines

Dental suction and gas analysis equipment

If your process needs stable air or vacuum, chances are the 4RB fits right in.

Why More Users Choose the 4RB Side Channel Blower

The real value of the 4RB blower is not just performance, but confidence. Confidence that it will work anywhere, last longer, and stay quiet while doing its job. For users who want one reliable solution instead of multiple specialized machines, the answer is simple.

Where are you planning to use your 4RB blower—pressure, vacuum, or both?
