Hi all
Yesterday I was asked about the effect of trying to reduce the closing
force of doors with oil-filled door closers, rather than the spring
mechanism type. This came about since I had generally recommend reducing
the tension on door closers to make doors lighter to open. The
maintenance person said that the only adjustment on an oil filled door
closer is to reduce, or enlarge the size of the aperture through which
the oil passes. However, the net effect of enlarging the hole whilst
making the door easier to open (less oil resistance through the
aperture) was that it would shut quickly as well (the oil flows back
quicker). No other adjustment being available.
If this is the case then recommending adjusting the door closer is going
create a problem as much as it solves one. Has anyone else come across
this issue?
Thanks
