Operating principle

SEAT Ventilation distributes a range of electronic frequency inverters to precisely match the fan speed to suit your installation. These units comply with the latest European standards and are complete with emc filters.

VARIASEAT VFDs are specifically configured for each SEAT Ventilation fan.

Providing motor protection in all applications, allowing the fan speed to be varied to achieve significant energy savings, and adaptable to all electrical installation requirements :

• Single-phase 230V input / Three-phase 230V output

• Three-phase 400V input / Three-phase 400V output

• Output frequency range: 15Hz to 60Hz

 

 

Why modify the motor speed ? 

Decreasing the motor speed allows to:

  • Achieve the exact duty point (CFM @ SP)
  • Reduce the airflow and static pressure in a more efficient way than a manual damper
  • Saves energy
  • Reduce noise levels
  • Protect the blower from power surges, harmonics, or any kind of electrical issues
  • Reduce the starting current by applying ramps
  • Significantly increase the blower lifespan energy

Features :

Our frequency inverters allow controlling the speed of our three-phase asynchronous or synchronous electric motors.

    Fantastically Awesome!
    Special Size: Wide Leg Crop, Size: 12, Color: Black
    They are spectacular! Very nice quality and I love how they fit. Got the black and ice blue. Having read the reviews, I did go ahead and sized up 2 sizes and it worked perfectly. That is the only con in these jeans, they run at least 2 sizes too small. But, being 100% cotton, I expect that they will shrink down to pretty close my normal size. (I like jeans loose, so it's all good.) Got the cropped ones and I just love them. They are normal length now (because I am short), but after drying, I think they will end up at top of my ankle, and that is cool. The fabric is on the heavy side, but I expected them to be much heavier than what I got. I have a pair of Lee wide leg jeans, and they are much heavier than these. I hope that helps someone in terms of comparison. But overall, these jeans are fantastically awesome - and on sale too boot!! Buy them. They are very wonderful. ❤️

    Insanely great jeans for the price!
    Special Size: Wide Leg Crop, Size: 12, Color: Medium Blue Vintage
    I’m obsessed with these jeans. They’re comfortable and I think they legitimately look great. I had a baby 6 months ago and my body is “in transition” so I didn’t want to buy anything too expensive. These are cute, fit well, good quality. Excellent for short girls - I’m 5’ tall and they’re exactly the right length for a full-length jean. I feel like they’re fashionable without being too trendy (they work for 30somethings as well as 20somethings). They’re nice thick cotton with very little stretch. Because of that I’d be conservative with sizing because they do stretch significantly when you wear them. I got these in the lighter blue, too. The darker wash is slightly smaller and I wound up liking the color better, too. But the light wash is nice.

    Excellant value
    Special Size: Wide Leg Crop, Size: 14, Color: Rinse, Special Size: Wide Leg Crop, Size: 14, Color: Rinse
    Purchased the “cropped” length. I am 5ft 3.5 inch. Weight 170lbs (42 inch hip/38 inch waist) normally wear a size 10/12 or 31 in jeans, depending on the brand. I ordered up at 14 for these based on other reviewers. (When held up to other jeans they were the same as a Talbots 10 at the waist) Prewash they felt good, a little big& length hit at the top of my foot. After wash and dry, the fit was almost perfect and the length was at lower ankle. Ordering up is probably the right choice, although I think I could have been comfortable in a 12 (with no drying). They are a tad bit too long for a “cropped” look IMO. The wide leg is a true wide leg and falls straight from the waist. The material is heavy and there is almost no give/stretch - so a traditional denim. This is the dark blue and it is a true dark blue. You can’t beat the price, excellent value.

    Be careful when washing!!!
    Special Size: Wide Leg Crop, Size: 12, Color: Iced Blue Light Wash
    Loved the jeans but after I washed them only after wearing one time, the color got completely stained. I washed on gentle with like colors and somehow the entire jeans turned splotchy. So upsetting because the fit and feel were great.

    Great Jeans!!
    Special Size: Wide Leg, Size: 8, Color: Stone Dark Wash
    I love these wide leg jeans! The denim is thicker and more durable than I was expecting, especially for the price. These are a great quality! I get compliments on them every time I wear them and people are surprised when I tell them they're Amazon Basic brand. They fit true to size as I followed the size guide. From now on my jeans will be this brand!
