B-LINE BLKNP40FL – Frequently Asked Questions
1) Will the Eaton B-Line BLKNP40FL filter fan keep my enclosure's NEMA 4 rating?
Yes. The BLKNP40FL bolt-on filter fan is itself rated NEMA 4, so bolting it to a NEMA 4 enclosure keeps the washdown/hosedown protection level intact. It is also UL/CUL listed. Eaton describes it as suitable for NEMA 4 or 4X enclosures.
2) How much flat panel space do I need to mount the B-Line BLKNP40FL filter fan?
Plan the cutout and clearance around a unit measuring 16.56 x 16.56 x 9.85 inches. That footprint rules out small junction-style enclosures, so check the flat door or side panel area before you order, and allow for the 10 lb hanging weight on the panel.
3) Does the BLKNP40FL fan match the gray finish on my existing B-Line enclosures?
It is painted ANSI 61 gray, the standard gray used across Eaton B-Line enclosure lines, so a bolt-on fan will read as the same color as the rest of a gray-painted lineup in a plant or control room.
4) Can I use this filter fan on a fiberglass enclosure, or is it for steel only?
The BLKNP40FL is part of Eaton B-Line's fiberglass accessory line, so it is intended for the fiberglass NEMA 4 and 4X enclosures in that series. The bolt-on mounting means you cut and drill the fiberglass panel rather than welding anything to it.
5) Is a filter fan the right choice, or should I be looking at a sealed air conditioner for my NEMA 4X enclosure?
A filter fan like the BLKNP40FL exchanges air with the surrounding room through a filter, so it only works when ambient air is cooler than the target internal temperature and reasonably clean. It cannot cool below ambient. If the enclosure sits in a hot area, or the surrounding air carries chemicals you do not want touching the electronics, a closed-loop air conditioner or heat exchanger is the correct choice instead. The NEMA 4 rating on this fan means the washdown protection is maintained where a plain vent would break it.
6) What model number do I order for the B-Line NEMA 4 gray filter fan?
Order Eaton B-Line part number BLKNP40FL. That is the single model covered, an ANSI 61 gray painted bolt-on filter fan for NEMA 4 or 4X enclosures.
