Frequently Asked Questions

Q1: Is this fan designed for true industrial 24/7 operation?

A: Yes. With its robust construction (21kg), industrial-grade motor, and components rated for continuous duty, the RH50V-4DK.6K.1R is engineered specifically for uninterrupted operation in demanding industrial settings, ensuring longevity over 10 years.

Q2: Why does the power nearly double from 1.25kW to 2.0kW at 60Hz?

A: This is due to the combined effect of increased speed (from 1360 to 1570 RPM) and the motor's torque-speed characteristics at different frequencies. It allows the fan to deliver higher airflow and pressure performance on a 60Hz grid to meet more demanding cooling or ventilation requirements.

Q3: What does the ".6K" in the model suffix indicate?

A: In ZIEHL-ABEGG's nomenclature, .6K typically denotes a specific version with enhanced features, which may include a special motor winding, higher insulation class, or specific electrical protection suited for particular voltage conditions or duty cycles. Refer to the official datasheet for exact specifications.

Q4: What are typical applications for this type of centrifugal fan?

A: Ideal for applications requiring reliable airflow against resistance, such as industrial oven cooling, fume and dust extraction systems, process cooling for machinery, and pressurizing large enclosures or control rooms.

The 4K's Rating
I'm not sure what's going on with this release, as it gets praised by some, condemned by others. Very strange. For me, all the criticism of the colors in some scenes (like the teal & orange bedroom scene) makes no sense, because those colors do not appear as saturated and forceful on my Panasonic 4K player and Samsung 42" 4K TV. They look noticable, as teal and orange naturally clash at any strength. But they don't look entirely unnatural. As for the grain, it iS awful during the initial party scene, to the point of distraction. But as the movie progresses, it seems to weaken. I'm not sure at what exact point the distraction ends, only that I became fully absorbed in the movie before Bill's nocturnal "adventures." (As a matter of note, I don't oversharpen in the settings, and don't bump up saturation.) This rating is for the 4K. I've only watched about 20 minutes of the blu-ray, during which I encountered a 3-4 second sound dropout that was troublesome. As in SILENCE. It's something I intend to contact Criterion about, to see if this is an anomaly (in which case I'll initiated a replacement from Amazon). If it's a general problem, I'll ask Criterion for a blu-ray replacement. I want to watch more of the blu-ray before taking any action, in case there are more dropouts to report. BTW, the blu-ray looks quite good to me, altho I think the 4K is slightly more detailed.

One of my all-time favorites looking better than ever!
Firstly, the bad (see pictures). I'm not knocking off any stars, because there's nothing wrong with the movie/4K transfer. If you see the 4K variant listed for cheap, be aware you may need to buy a new case, which for a single is roughly $8-$9 per, and $22 if you buy a pack. I had a case, and just moved the slip cover over. Not ideal, but... If I didn't have a spare case I would've had it replaced. For a movie that's special to me as this one is I'd prefer to have the OEM case. Something just feels less authentic knowing I had to transfer a movie (one of my all-time favorites) that recently got a 4K transfer, into another case. Just be aware of this if you see it pop up for sale on Amazon for a low price. It's possible it could have something to do with shipping, but this was shipped from Amazon. I just don't "think" it would be crushed so bad to break the plastic housing into pieces on the top, bottom, and bottom of the spine from shipping. The seller may not have shipped it in this condition, but I assume they did, or I wouldn't imagine it would've been listed as cheap as I got it for. I'm not knocking the seller or Amazon. It was a great deal overall, but maybe not so much so if I hadn't had a spare case. The improvements to the 4K variant are very good. The contrast and black levels are drastically improved over the HD Blu-ray. Colors are better, and the overall transfer just looks great. It's a genuine 35mm transfer, and with the resolution boost I can see things in this movie now that I don't ever recall being able to see before. I may be redundant here, but truly, the black levels of the suits are excellent. No more gray looking suits. The overall contrast of the film is greatly enhanced. Film grain: I think this is important to mention, because it won't be long before 120+ inch TVs are more widely available, and affordable. I'm viewing this on a 120" screen projected from a Sony laser projector, and I'm not saying that as a humble brag. I'm simply saying I realize most will be viewing this on smaller screens at the time of writing this review, and the film grain will be less evident for the average viewer. Even at 120" it looks good. Too many details may have been scrubbed away if they tried to remove all of the film grain, and it would lose that 35mm look. Now, Jurassic Park 4K? I have to watch it on a smaller screen to be bearable, because the film grain in Jurassic Park 4K is intolerably bad for my liking. For anyone who owns and enjoys older films that are really special to you, never get rid of your smaller screen if you do eventually move up to 100+ inches, because even as horrible as the film grain is on Jurassic Park 4K at 120", it looks like it was shot yesterday when I watch it on a 65". I imagine Dark City 4K would look amazing on anything below 100" (unless you sit really close to the screen), but again, it still looks really good to me at 120". This film is one of my childhood and all-time favorites. I won't write a review explaining the movie itself, because I imagine most people who are reading this have already seen and love this film, and are only looking to see what the improvements are for the 4K transfer. Search YouTube "Dark City 4K Vs HD" for really good side-by-side comparisons so you can see just how much they put into this. I think the channel name is "Twin Flicks" that I watched the comparison on before purchasing this/Dark City in 4K. I highly recommend the 4K variant of Dark City from Arrow. I'm not really qualified to say, but I think they did a great job with this transfer.

Cult classic for a good reason
This movie has attracted a enthusiastic following over the years. It has a great story, deeply developed characters, and clever plotting. The 4K disc picture quality is excellent, as is the sound. It's a movie I watch regularly over the years, which is the test that counts—repeat viewings (there is always some new detail to discover, and others to appreciate).

An Archival quality 4k
The Director's Cut is marvelous and this new 4K release is sensational. The image quality is remarkable and yes, noticeably superior to the Blu-Ray release. The audio is also worth mentioning here, so do not think you will be in any way disappointed. While the price is a bit step, I just waited for a good sale and nabbed it at 50% off.
