If you’re looking for an airflow solution in your industrial process application, you might be curious as to the difference between an industrial fan and an industrial blower. However, your question is a trick question, because there’s actually no difference between an industrial fan or blower at all. The two products’ designs are the same.

The truth is, in industrial processes, a fan or blower is not defined by the design or style of the impeller, but rather which side of the fan offers the resistance the fan must overcome to move air from one area to another.

So what is the difference between a blower and a fan?

So there is a difference between a blower and a fan, but it’s really one of placement more than anything else:

• an industrial induced draft fan sucks air through a system and discharges it to the atmosphere
• a forced-draft or pressure blower sucks atmospheric air from outside and blows it through the system

 

In non-industrial systems, such as free-standing commercial or residential applications, there are a few other differences between fans and blowers as well.

Do I need an Industrial Fan or Industrial Blower?

Which machine you need depends on that machine’s function within the application. If the application requires lower volume and higher pressure, such as a burner, air dryer, fume or gas elimination, or others, you’ll need a forced-draft or pressure blower with volume and pressure focused at the outlet. If your application calls for other combinations of volume and pressure, you’ll probably want an induced draft fan with volume and pressure focused at the inlet.

Regardless of which you need, or if you’re unsure if you need an industrial blower or industrial fan, the experts at Safe Air Technology are here to help! We’ve been manufacturing explosion-proof blowers and fans, along with other air moving technology, for years, and we specialize in heavy industrial and offshore plants.

Your commercial HVAC system is made up of a number of interconnected sub-systems and parts. One of the most important components of your HVAC system is called the Air Handler Unit, or AHU. The AHU is the internal partner to the Condensing Unit, which is the big metal box outside your business or on the roof with the fan. Here’s how they work together to cool your home and business.

Basically, an HVAC system works to shift heat from inside your building to the outside. The first law of thermodynamics states that heat energy can neither be created nor destroyed; rather, it must be moved outside, where it can dissipate into the air. 

That’s why a commercial HVAC system has components on both the inside and outside of your building: the inside Air Handler Unit pulls heat from the air as it’s forced through the ducts and transfers it to the refrigerant, a special chemical which can absorb and release heat effectively. The now hot refrigerant, in gaseous form, travels through a refrigerant line to the Condensing Unit, which allows the refrigerant to radiate its heat to the outside air, condensing into a liquid in the process. Then, the refrigerant cycles back inside to get heated again.

Air Handler Anatomy

Air filter

Before the air in your building enters the Air Handler Unit, it needs to be cleaned to remove contaminants that can gum up the works. The air filter, which sits between the fan and intake ducting, does this important job.

Evaporator Coils

Once through the filter, the air passes over the evaporate (or indoor) coils. These coils contain refrigerant gas, which absorbs the extra heat latent in the air and cools it. If the Air Handler is the heart of your interior HVAC system, this is the heart of your Air Handler.

Blower

After the air is cooled (or “conditioned,” as in “air conditioner”), the blower fan within the Air Handler circulates it out of the Air Handler and into the ductwork, whence it is distributed throughout your office, warehouse, or factory as cool, conditioned air.

Why is an Air Handler Unit important?

The AHU, when coupled with the outdoor Condenser Unit, is the part of your HVAC unit that actually serves to cool the air circulating through your building. If the AHU doesn’t exist or fails, your commercial building basically just has an expensive fan system blowing tepid air around. That’s why regular maintenance and upkeep of your HVAC system is vitally important to the continued functioning of the system, and indirectly the functioning of your business as a whole.

Modern HVAC systems do more than cool the air. They also filter the air of contaminants like common allergens, air-borne pathogens, and toxins, keeping the air quality in your business high. A well-functioning HVAC system is also more efficient, which saves you money month-to-month in your utility bills.

The AHU helps keep the entire process of capturing excess heat from inside your building and circulating it outside energy efficient and effective. In addition, AHUs are highly important to the safety of your building. 

Irregular circulation within your HVAC system can cause frost that can damage equipment, leading to excessive condensation inside the building. Extra liquid can pool on the floor, causing slippage, or can short important electrical equipment. A properly working HVAC system requires a floor drain or condensation box to keep everyone who works for you safe.

The Takeaway

Unless you’re an HVAC technician, you probably only think about your HVAC system when it fails. However, a properly-working HVAC system is key to keeping the temperature inside your building safely regulated, which keeps your employees happy and healthy, and saves you money on your utility bills. Make sure to keep your entire HVAC system, especially the Air Handler Unit, properly serviced and cleaned.

You need a well-designed Air Handler Unit to help your HVAC system perform optimally. At Safe Air Technology, our expert HVAC engineers can design and build certified explosion-proof Air Handlers for your industrial needs. We can even customize your AHU to fit the size and shape of your operation. Contact us today to get started selecting or customizing an explosion-proof Air Handler today.

A condenser unit is an essential part of any HVAC system. To put it shortly, the condenser unit releases superheated air that is generated during the air circulation process. How you get superheated air while cooling your building can get a bit complex but knowing the basic parts of a condenser unit and thinking of air heating and cooling as a circular motion makes it much easier to understand.

Condenser Anatomy

 

Condenser box – Most of us recognize this as the loud box behind a house or building that controls the AC. The inside condenser walls are made up of coils that circulate very hot refrigerant (more on this below), releasing excess heat.

Compressor – This is located inside of the condenser unit and is considered the heart of the HVAC system. Compressors pump refrigerant in a closed loop of cold vapor to hot liquid and so on.

Fan – Located at the top of the condenser, the fan helps release excess heat built up inside the condenser coils.

The Takeaway

We know condenser units aren’t particularly attractive, but they’re the key to keeping the temperature inside of your building safely regulated, saving you money on utility bills, maintenance and equipment in the long run. Keep it clear of debris and other obstructions to keep your HVAC system in top shape for years to come.

At Safe Air Technology, our expert HVAC engineers design and build fully certified commercial-grade condensing units. We can even customize the right size condensing unit for your building. Give us a call to get started on finding or building the right condenser unit for your business.

Spring is upon us, meaning it is prime time to clean your HVAC system! As we approach more mild weather, heating and cooling systems should not be used at their maximum capacity. This in-between season is a great time to have your system serviced and cleaned of dust, debris, or any other general maintenance. By keeping your unit clean, you preserve the longevity of your system’s lifespan and prevent contamination of indoor air. At Safe Air Technology, we work to provide explosion proof HVAC equipment to meet the needs of today and the future. By ensuring your system is in good working condition, your organization can have peace of mind.

When cleaning an industrial HVAC unit, all internal components should be inspected and cleaned. A good HVAC maintenance checklist should be as followed:

• Keep your building clean, accumulated dust will be recirculated
• Ensure all ducts are flowing freely, with nothing blocking or excess dirt
• Make sure outside HVAC unit is free of leaves or other debris
• Pay attention to any possible performance issues (i.e. weak airflow)

 

The more people in your facility means the more you need to change your air filters. Operating your commercial HVAC equipment with a dirty or clogged air filter can result in damage to your system and to people’s health. By changing filters on a regular basis, you can prevent significant monetary losses from the rising energy costs of a poorly-functioning unit. While a dirty HVAC system does not necessarily produce unhealthy air, it could cause serious issues to people with respiratory issues, autoimmune disorders, or environmental/seasonal allergies.

Another component of industrial HVAC systems that often goes overlooked are drain pans. These should be cleaned frequently to prevent water accumulation that could lead to mold and bacteria growth. If a drain pan issue goes unnoticed, it could result in serious damage to your HVAC system.
