What are Some Points to Consider when Buying Fans for Ventilations?

Choosing the best fans for ventilation can be a difficult task. Everyone has their own choices and ideas of how ventilation fans should look. After all the details have been established such as duct type, fresh air, and diameter, it is time to think if the business will get the end results that can meet the performance goal as well as specific environmental requirements.



Here are some of the points that you must keep in mind before choosing the fans for ventilation for your business:

 

Noise Sensitivity

Noise is one of the major components of the ventilation fans. While working in an urban environment, this is the most critical problem. To overcome this problem, there are many ways to minimize this. One of the best effective methods to control noise is adding an inline silencer.

 

Additionally, adding a silencer is not enough. Many manufacturers that provide ventilation fans in Singapore offer fans built with integrated silencers. The advantage of the design of a silenced fan when compared to a standard fan with two silencers, will be shorter and easy to handle.

 

Motor Selection

An appropriate motor should also be considered while choosing the fans for ventilation. The ventilation fan must meet the local regulations covering and gassy conditions or possibly flammable dust. Extending ducting and moving fans is an essential part of the process. it is not important to design a ventilation system, but it should also be implemented perfectly.

 

One thing also to be considered that there is a reasonable cushion between the motor’s rating and the calculated load. A common service factor for ventilation fans in Singapore is 1.15, which means that the motor can operate at 115% of its rated load. Some of the manufacturers use non-standard mounting and shaft designs that require replacement motors to be highly modified which may be good for the long-term.

 

Service

A supplier should manage the products and provide warranty claims and the claim fall under the motor warranty. Also, they should have the parts in their stock when an object destroys the fan motor. A supplier should help you and solve your problems immediately.

 

Price

When purchasing the ventilation fans, the price should be taken into account when choosing a supplier.

 

Performance

While choosing the fans, the performance parameters must meet the requirements. It is a simple combination of volume (CFM or equivalent) and pressure (inches of water gauge or equivalent). One condition that is critical to the fan’s longevity is where the fan’s performance curve is the operating duty point. If the duty point is approaching the zone of the fan, one small change to the system can push the fan into a stall condition.

 

The fan’s efficiency must also be considered. Within a single manufacturer’s range of offerings, there can be more than one model that can meet the required performance.

 

Maintenance

The ventilation unit must be cleaned at an interval of 3 to 6 months. You will learn to know the maintenance interval required by the unit, but many models also have a maintenance reminder. Also, the need for maintenance depends on the residential environment.

 

Taking into use

When a ventilation fan is purchased, it is always necessary to agree with the supplier on the adjustments of the fan. The implementation of the fan involves the guidance and information of the operating speed 

of the unit in order to make sure sufficient ventilation in different conditions.

What is the difference between commercial fans and industrial fans in Singapore?

Image
  Commercial and  industrial fans in Singapore  might appear to be the same; the only difference is how they are made and how they work. Also, the main difference between them is driven by the cost. Commercial fans use the least expensive materials and components and are designed for the residential or light-duty commercial markets. These fans are also used in homes and small ventilation systems.   On the other hand,  industrial fans in Singapore  are  giant fans , which circulated a greater airflow and pressure and met more stringent environmental and ambient requirements. Now, let's understand the difference between commercial fans and  industrial fans in Singapore :   Axial fans Axial fans consist of several parts, such as the motor and the blades where the air is distributed. The easiest thing to note between the two is the materials used for each. Commercial fans or general-purpose fans are made from light gauge sheet steel. ...

  What is HVLS fans ? HVLS fans, as the name suggests, High-Speed Low Volume fans, are those who are big in size, but they move slowly. They are used to circulate the air on the areas where air circulation is much needed. These large, slow-moving fans can save you a lot of energy when they are used correctly.   Here are some of the tips in which you can maximize your ROI by hiring the right  HVLS fan supplier in Singapore : Use HVLS fans in Winter During colder months, many factories often have more than a 20-deg,-F difference between the floor and ceiling. Typically, the air temperature will be 0.5 to 1 deg.-F more heated for every measure in height. A heating system must work hard for long periods to sustain the temperature near the floor or waste costly energy and dollars at the thermostat set point. Using HVLS fans can be easy if you choose the right  HVLS fan supplier in Singapore . They will guide you with all the fan's controls and features, which you ca...
