    You are mistaken the CLS 1840 has a cooling system.

    From what I can tell, the CLS1840 is similar to the CLS2000 pictured here.

    The CLS1840 is similar to that picture, except... only 1 cooling fan (the upper one), and the top sheet metal "lid" has no provision for an exhaust hose (no metal flange to connect the hose). The exhaust air on the CLS1840 exits the "lid" through louvers.

    Efficient cooling is essential to any colorhead.

    Yes, I found the CLS1840 schematic and it only shows the single Lufter (fan).

    Out of curiosity does the CLS1840 have this opening that blows on the negative holder?

    Here is a CLS2000 setup on the "Footprints" brokerage site. Not too bad at $4000USD. I got just about the same setup with the Negateil, the mixing boxes and a box of lenses with around $2000USD involved. That was about ten years ago.

    Confused. I just acquired a CLS 1840 enlarger and it came with a top plate that connects to a 90 degree hose mount to connect to flexible metal pipe so that an external blower motor can push air into the top of the unit. How do I check if it already has a blower motor in there. Is this overkill and could I have a higher wattage bulb requiring this configuration? Thanks.

    Pushing air into a exhaust with a extra blower don't seem a good idea.
