Frequently Asked Questions

Negative pressure ventilation uses exhaust fans to remove air from a building. As indoor air is exhausted, replacement air enters through designed openings, creating a continuous airflow path through the building.

The exhaust fan removes air from the building, while fresh air enters through doors, windows, louvers, cooling pads or dedicated air inlets. Proper fan and inlet arrangement creates the desired airflow through the space.

An exhaust fan is designed primarily to move air out of a building. An air circulation fan primarily moves air within the building to improve air distribution and comfort.

Consider the building size, application, required airflow, installation location, environmental conditions, electrical supply and desired ventilation method. For project selection, providing building dimensions and application details is helpful.

FRP fans can be considered where corrosion resistance is an important requirement. Selection should consider the specific chemicals, humidity, temperature and environmental exposure of the application.

201 and 304 are different stainless-steel grades with different alloy compositions and corrosion-resistance characteristics. 304 generally offers better corrosion resistance, while 201 can be considered for applications where the environmental requirements are less demanding.

For demanding or corrosive environments, the appropriate grade should be selected based on the actual operating conditions.

Yes. They can be used to remove heat, stale air and other unwanted air conditions. The appropriate system depends on the manufacturing process, heat sources, building structure and ventilation requirements.

A shutter or louver is the opening/closing structure associated with the fan’s air outlet. It helps control the opening when the fan operates and can help close the opening when the fan is stopped.

The shutter design affects airflow, sealing, durability and the way the fan operates when starting and stopping. Construction and material selection should therefore be considered when comparing exhaust fans.

A hanging fan is suspended from a suitable structure and is designed to circulate air through a defined area. It can be useful where floor space is limited or where elevated air movement is preferred.

It is a hanging air circulation fan designed for livestock environments, where air movement can help improve ventilation and thermal comfort around animals. Fan selection should consider the building, animal type and environmental conditions.

HVLS stands for High Volume Low Speed. HVLS fans use large-diameter blades to move a large volume of air at relatively low rotational speed, making them suitable for many large open spaces.

HVLS fans use a large-diameter, low-speed design to distribute air across a broad area. Conventional industrial fans are available in many configurations and may provide more localized or directional airflow.

A fixed air cooler is installed in a designated position and may supply air through a duct or air guide. A portable air cooler can be moved between locations and is useful for spot or directional cooling.

It is a compact unit integrating the fan, cooling pads, water system and other components into one cooling unit. It provides cooled air directly from the unit.

Yes. This is a common system approach for negative-pressure evaporative cooling: cooling pads provide cooled incoming air while exhaust fans remove warm air from the building.

Consider evaporative cooling when you want fresh-air cooling, the climate is suitable for evaporation, and some increase in indoor humidity is acceptable. Building layout and ventilation should also support the system.

A portable industrial air conditioner is designed to be installed and used with greater flexibility, often allowing cooling to be moved between areas. Conventional systems are generally designed as more permanent installations.

Consider the space size, heat load, indoor conditions, application, required cooling capacity, power supply and installation arrangement. For project selection, provide building dimensions and application details.

Building dimensions determine the amount of air contained within the space and influence the airflow required for the desired air exchange. Building height and layout are also important.

Walls, doors, windows, equipment, partitions, air inlets and heat sources all affect how air moves through a building. Fan location and airflow direction should therefore be considered as part of the system design.

Climate influences the effectiveness of evaporative cooling, the cooling load of the building and the suitability of different technologies. Local temperature and humidity are particularly important when comparing evaporative and refrigerated cooling.

Choose according to the primary objective rather than the product name. If you need to remove air, consider exhaust ventilation; if you need to move air, consider circulation fans; if you need fresh-air evaporative cooling, consider evaporative coolers; and if you need refrigerated cooling, consider industrial air conditioning.

Yes. Depending on the application, exhaust fans, circulation fans, evaporative coolers and air conditioners can form part of a broader cooling or ventilation system. The equipment should be selected as a coordinated system.

Yes. Portable drum fans can provide directional airflow in warehouse work areas, loading zones and other spaces where movable air circulation is useful.

Depending on the model and cooling requirements, yes. Industrial/commercial air-conditioning equipment can be considered for larger or open commercial spaces where appropriate cooling capacity is required.

MX Cooling offers multiple categories of cooling and ventilation equipment. For project requirements, customers can provide building and application information so suitable products and configurations can be discussed.

Fan performance can be affected by fan design, airflow resistance, installation arrangement, air-inlet conditions, ducting where applicable, environmental conditions and operating conditions.

Static pressure is the resistance a fan must overcome while moving air through a system. It becomes particularly important when air must pass through restrictions such as ducts, filters, louvers or other components.

Static pressure matters whenever airflow encounters meaningful resistance. For open-wall exhaust applications it may be less significant than in ducted or highly restricted systems, but it should still be considered during engineering selection.

Two fans with the same physical size can have different airflow, pressure characteristics, motor configurations and operating performance. The correct selection depends on the required operating conditions, not just dimensions.

Availability depends on the product and project. Contact MX Cooling with the model or application requirements to request the relevant documentation.

Yes. Provide the product type, desired size or model where known, quantity and application. This helps the team identify the relevant information.

MX Cooling is a ventilation and cooling equipment manufacturer. We do not provide on-site measurement, installation or commissioning services. However, customers can provide building dimensions, application details, operating conditions, drawings or photos, and our team can recommend suitable product types, models and estimated quantities based on the information provided. Installation and site-specific engineering should be handled by the customer or a qualified local contractor.

Provide the application, product type, required dimensions, materials, electrical requirements, quantity, destination market and any drawings, photos or existing-product references available.

Typically, the product type, model/size, configuration, electrical requirements, quantity and destination are needed. Additional technical information may be required for customized products.

MX Cooling is positioned as an industrial cooling and ventilation manufacturer serving international customers. For a specific destination, contact the company to discuss product, shipping and documentation requirements.

Provide the destination country, city/port where relevant, electrical voltage/frequency requirements and any known import or certification requirements.

Many MX Cooling fan families include multiple sizes and configurations. Presenting the family on one page and providing detailed model information through the catalog makes it easier to compare the range without creating dozens of nearly identical pages.
