    Dwy 1950 20 Diff Press Sw 4.0 Inch -20 Inch Wg
    DWYER 1950 20 DIFF PRESS SW 4.0 Inch -20 Inch WG Model 1950 Explosion-proof Differential Pressure Switch combines the best features of the popular Dwyer Series 1900 Pressure Switch with an integral explosion-proof and weatherproof housing, making it an exceptional value for either application. It is CE, UL and CSA listed, FM approved for use in Class I, Div 1, Groups C and D, Class II Groups E, F, and G and Class III hazardous atmospheres NEMA 7 & 9. Raintight NEMA 3 (IP54). Weatherproof features include a drain plug and O-ring seal in cover. Electrical connections are easily made by removing front cover. For convenience the set point adjustment screw is located on the outside of the housing. Twelve models offer set points from .03 to 20 w.c. (7.5 to 5 kPa) and from .5 to 60 psi (0.035 to 3.5 bar). The unit is very light and compact - about half the weight and bulk of other explosion-proof or weatherproof switches with separate enclosures.

Feedback
Brilliant service, thank you. Robin
...Robin Bass
The DELABIE Shower head holder in chrome metal dia. 25&32mm is now fitted and provides a robust and stylish answer for replacement shower head holders. The original abs plastic equipment failed, the replacement abs plastic failed this one now seems to be the business. Order responses, information and prompt delivery are all well provided by MyTub. Good experience all round.
...Robert Archer
I found the Mira shower Slider at a good price and had free delivery even if it did take 10 days. Fine if not an emergency situation.
...Mr John Lacy

...David Cooling

...Catalent Australia
First rate service, no complaints or adverse comments
...JAMES FLATT
Competitive and efficient. Will certainly consider using you again and would recommend you.
...Mr John Ashmore
The courier has tried to deliver my parcel twice but despite me putting a message on the order, which you acknowledged the courier wont leave the parcel so I am still waiting! If I was honest the whole shopping experience with mytub has been a bit of a disappointment. I was told the item was in stock yet you gave an estimated delivery date of 10 days later. However you did change this to the 1212 after I emailed you which was good of you. But now I am now in the position of having to stay in all day Monday waiting for the courier to deliver despite you noting my message that the parcel could be left.
...Ian Tate
Thank you for your excellent service - I will definitely use you again and recommend you to family & friends !
...Andrea Burns
