Low-pressure centrifugal fans VC 4-76

Radial Low-Pressure Fans VC 4-76: Effective Solution for Industrial Systems

The VC 4-76 series consists of centrifugal low-pressure fans designed for large-scale technological networks. The purpose of these devices is the stable movement of air and gas mixtures at temperatures specified in the model characteristics. You can buy a high-quality VC 4-76 fan at Ventilator.ua — the Ukrainian online store for ventilation and motors. The catalog features a wide range of VC 4-76 low-pressure fan modifications made of carbon steel in standard and heat-resistant versions.

What are VC 4-76 low-pressure fans and where are they used

VC 4-76 is an industrial cycle of radial solutions designed for moving air and gas mixtures in systems with long air duct extensions. Typical applications for VC 4-76 fans include:

• workshop ventilation;
• dust stream aspiration;
• drying processes;
• heating systems requiring a large volume of air at moderate static pressure.

The line includes models for general aeration, aspiration, air heating, and conditioning, ensuring long-term operation in intensive cyclic load modes. Options are available for both standard conditions and elevated temperatures (so-called heat-resistant VC fans).

Design features of VC 4-76 fans

The frame and casing of industrial VC 4-76 fans from KVZ are built to withstand industrial network loads: carbon steel is typically used, while stainless steel is applied for aggressive or high-temperature environments (on request). It is important to note that the choice between stainless steel and carbon steel depends on the level of gas environment aggressiveness and requirements for the device's temperature resistance. The units feature 12 backward-curved blades for the required aerodynamics. The design includes reliable bearings and allows for quick maintenance. The impeller rotation direction (right or left) is chosen based on the duct layout and inlet location.

Technical parameters of VC 4-76 fans:

• electric motor power: from 15 kW (AIR 160 S4) up to 132 kW (AIR 315 M6);
• capacity: from ~22,510 m³/h (VC 4-76 No. 8) to ~139,000 m³/h (in heat-resistant model No. 20 Ж);
• pressure: from ~883 Pa (VC 4-76 No. 16) up to ~3000 Pa (No. 14 Ж);
• impeller sizes: VC 4-76 No. 8, No. 10, No. 12.5, No. 14 Ж, No. 16, No. 20 Ж;
• rotation speed: typically 1,000 or 1,500 rpm, depending on the model;
• impeller rotation direction: right-handed/left-handed;
• casing material: standard carbon steel and heat-resistant in Ж modifications;
• suction: single-sided;
• air contamination: maximum dust content no more than 100 mg/m³, provided no sticky or fibrous materials are present;
• execution scheme 5 (V-belt drive): for most models.

This series solves tasks where reliability and stability of air and gas mixture movement are critical. We invite you to buy a centrifugal low-pressure fan in Kyiv at the best price. Delivery is available not only to Ukrainian cities but also abroad to Europe and Asia.

For various climate zones

Kyiv Ventilation Plant produces VC 4-76 series carbon steel fans primarily oriented for moderate climate conditions (marked У). The standard version is У2, which corresponds to placement category 2 according to GOST 15150. This means the equipment can operate under shelters or in unheated rooms where conditions are close to outdoor but without direct exposure to precipitation or sunlight. Also, depending on the modification, the VC 4 fan can be designed for tropical conditions (T).

The typical temperature range for У2 execution is approximately -40 °C to +40 °C. For VC 4-76 No. 20 (execution 5), the standard temperature is up to 80 °C. Besides the basic version, the plant also produces heat-resistant fans — VC 4-76 Ж, designed for moving hot air and gas mixtures (up to 200 °C). These fans are built for stable operation in real environmental conditions where temperature, humidity, and dust parameters may change seasonally.

VR-89-76 — what is it?

The VR-89-76.1 analog corresponds to the well-known VC 4-76 model, as these designations are used for the same line of radial fans. Both marking variants describe equipment with completely identical aerodynamic parameters and design characteristics. The name difference is only due to changing standards: the old designation is VC, and the modern one is VR 89-76, but technically it is one series of fans with identical properties.

Main advantages of the VC 4-76 series

The series combines efficient aerodynamics with ease of installation and maintenance. A correctly selected VC 4-76 fan will withstand intensive cycles and ensure long-term operation without frequent repairs. The spiral casing geometry increases efficiency when moving flows in networks with high duct resistance. Construction from durable steels guarantees long service life and mechanical stability. Advantages of buying a VC 4-76 low-pressure fan from "Kyiv Ventilation Plant" LLC:

• high performance with low energy costs;
• stable operation in air heating and ventilation modes;
• material variability (carbon or stainless steel);
• reversible rotation direction during installation;
• adaptation to dust content within permissible values;
• quality guarantee, good price, delivery across Ukraine, and developed international logistics.

Real-world operation at industrial sites shows that VC 4-76 fans demonstrate stable performance even in complex technological drying and aspiration lines.

Popular VC 4-76 models

Each centrifugal fan model has its purpose: compact sizes for local exhausts, medium for workshop networks, and large for main systems. The following modifications are frequently ordered from KVZ:

• VC 4-76 No. 8 with 15 kW motor, 1500 rpm, execution 5 — a compact and economical choice for small systems;
• VC 4-76 No. 10 with 45 kW motor, 1500 rpm — for large air ducts and increased capacity;
• VC 4-76 No. 20 Ж (heat-resistant fan), 55 kW motor — for flows with elevated temperatures and aggressive gas mixtures.

How to choose a VC 4-76 series low-pressure fan

Choosing a fan should start with system requirements: operating pressure, network length, and flow character. Also, the collector plays a vital role in industrial ventilation systems, so when selecting a model, its geometry and the possibility of correct coupling with the fan inlet must be considered. Important parameters for choosing a VC 4-76 fan:

• operating pressure and capacity;
• type and power of the electric motor;
• casing material;
• execution scheme;
• permissibility of dust and other solid particles content;
• rotation direction and compatibility with existing collectors;
• heat resistance (if operation at elevated temperatures is required);
• inlet dimensions and impeller balance (front and back disks).

An engineering flow assessment determines if the industrial VC 4-76 fan is suitable for a specific technological unit or heating system.
