AlorAir Storm LGR Extreme Features
The AlorAir Storm LGR Extreme has an extensive feature set. Here’s the features we found most compelling.
Performance
AlorAir created the Storm LGR Extreme with both performance in mind. The unit has a very high COP (coefficient of performance) of 2.8L/Kwh which translates to 5.2 pints/Kwh or .74 gallons/Kwh.
All things considered, the Storm LGR Extreme is capable of 85 PPD AHAM and 190 PPD saturation. That’s at 210 CFM, and more than respectable, especially when considering the unit’s compact size.
In fact, for portable commercial dehumidifiers with an integrated pump, it’s at the sharp end of the field. Speaking of, the pump is good for a 20 foot lifting distance. Water can be pumped away using the included condensate hose, too.
The unit also has a wide temperature and humidity operating range. For temperature, the unit is good from 33.8° to nearly 105° F (1° to 40° Celsius). As far as functioning humidity range, AlorAir states 35 to 95 percent humidity.
High performance across the operating range is the sum of many engineering factors. There is, however, one obvious hint. It’s actually right in the product’s name: LGR. Running R410A, an LGR, or low-grain refrigerant definitely helps.

Usability
Usability is a strong point for this AlorAir unit. First, you can submerge the base of the unit in water. The base is watertight and its the dehumidifier’s circuitry is sealed. Second, the unit has memory starting. Enough said. Third, the dehumidifiers LCD panel is crisp while admittedly lower tech. Lower tech is good for this type of equipment. The buttons and controls are confident if not familiar and make sense. Operation? Plug it in, select the setting you want and walk away.
Finally, while weighing it at 78 lb., moving and positioning is manageable. Tough handles are included on each end to position, or even hang the unit in a tight space.
It is worth noting, however, that the unit lacks wheels. While a shortcoming to many, what is great is how well the units stack.
Moving several? This picture from AlorAir’s site read our mind. Use a dolly, hand truck or cart. Sure, wheels sound great. But, being able to stack up several units doesn’t hurt either. It’s a tough call, but we’re okay with the lack of casters.
Maintenance and serviceability
This is a low maintenance unit. Aiding in that achievement is a MERV 8 filter. Positioned at the intake end of the dehumidifier it keeps dust and other particles out of the unit. Less dust and dirt in the unit means less buildup on coils.
That filter? Don’t worry, it is washable. It can quickly be slid out of the unit, hosed off and replaced. When operating in extreme environments, a HEPA filter can be used in the MERV 8 filter’s air inlet position.
AlorAir epoxy powder coats its coils. Thats extra insurance against refrigerant leaking. It also extends the coils’ ability to transfer heat. AlorAir recommends servicing the coils annually with any approved, self-rinsing coil cleaner.
When it does need to be serviced, access is easily achieved with hand tools.

Can you set this units gauges and let it run continuously? This will be in a craw space. Access is adequate but not something you would want to do fairly regularly . Thank you
Lori – Yes, you can. However, for what you are describing, I think you might be better served with a slightly different unit. This AlorAir unit is intended for crawlspace installation permanently whereas this unit can do that, but is designed for post-flood damage work.
This AlorAir setup can be installed with an optional (if you scroll down to the “Often Bought Together” section) remote control panel allowing you to adjust it whenever you need to without going up into the crawlspace.

My crawl space is rather low ceilinged and quite crowded with ductwork and supports. I live in middle TN and humidity is a “THING”.
Can I lay it on it’s side and drag it into place then set it upright without damaging the operation of the unit? I can drag it across a blanket or carpet runner but that’s as good as it gets.
I intend to leave it in place permanently as access is actually painful.
Is this the right unit for my planned application? If not, can you recommend? The built-in pump for drainage is imperative. I absolutely cannot do without an onboard pump. Neither can I dig a sump to install a sump pump.
Hey Michael –
While this would work, for a permanent mount and having the ability to control the unit remotely, I’d recommend looking a this Santa Fe unit over at Sylvane. It comes with everything you need and is designed for your exact application. Do note that it is priced with and without the Crawl Space Package.
I looked at what else as available over on Amazon, and they don’t have anything that is better than this Santa Fe. If this one isn’t ticking all your boxes, check out the rest of their crawlspace units. I saw some less pricey Ebac units that might work, too.
Sylvane is a great retailer, too, by the way. Click on the Chat button if you have any questions when you’re on their site – they’re very helpful.
