Spider Farmer 4 Inch Smart Inline Duct Fan with GGS Temperature Humidity Controller, Integrated App Control, 205 CFM Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics

Immagini ingannevoli dove viene mostrato il Ggs nuova versione con funzione da smartphone al suo posto mi è arrivata la vecchia versione che ovviamente non ha la funzione da smartphone motivo per cui lo avevo acquistato!! Penso proprio che farò il reso per articolo non conforme a quello pubblicizzato!

I have a couple competitor fans that are of similar style, they either run full speed or have an analog turn dial speed controller, all are 4", I'd say the Spider at 50% puts out almost as much air as the others on full speed. I'm using it to pull air from a server rack, my temporary installation of the fan, it's a bit louder than it should be because of my ducting on one side and the lack of it on the other, plus it's 22" away from my head. Back to the controller, I like how you can can control lights, vent fan, blower fan, not that I'm using the others, but it's nice it can be done from one spot. I'm doing it by temp, I set 40% always on speed and a ramp up to I think 60% above 28C. Once it's in final home I'll tweak the settings a bit more. If I had to list 2 "wishes". 1. i wish I would have gotten the model with the mounting cradle vs the sling. 2. I wish the fan ramp up was more of a ramp up, like a PWM in a computer where ok it's at 40% and 24C, oh it's 25C now, lets ramp up the fan a little to say 45% to see if it'll bring them temps back down rather than wait til 28C and instant full 60% or 100% if that's what you set it to.

Materiali di buona qualitá, assemblati bene. Avevo preso un’estrattore simile ma economico..faceva rumore, contatto al potenziometro, quindi si spengeva se toccato.. il rotore era continuamente in vibrazione… Questo sicuramente è silenzioso e con potenza decisamente superiore, vale i soldi spesi!

Erg makkelijke en krachtige ventilator! Met degelijke controller en erg licht van gewicht. Loopt traploos op en af, makkelijk in te stellen en doet wat ie moet doen. Weinig geluid ten opzichte van de normale afzuigers.

My fan did not come with an mounting bracket.
